LRS and Road Condition Survey Procedures Manual
PREFACE
The Location Referencing and Road Condition Survey Project has been completed as
a component of the Third Highway Improvement Project under Word Bank Credit
No. 2943-LA.
The five main objectives of the Project are:
1. To complete a location referencing survey of all National and Provincial roads
(estimated at 16,000km) to provide accurate chainages of nodes and intermediate
LRP’s on which all subsequent surveys can be referenced.
2. In conjunction with the location referencing survey, complete an automated road
roughness survey and visual condition rating and inventory collection survey.
3. Establish and document the data collection procedures for condition rating so that
they may be used in subsequent surveys by local Lao PDR staff.
4. To supply the data collected in a format that will allow it to be utilised in a future
road management system.
5. To support knowledge transfer to local staff to ensure the systems ongoing
integrity.
This report is one of three generated during the course of this project.

SCOPE OF DATA COLLECTION
1.1
Establishing the Survey Extent
The status of available Roading network information varies between provinces. In
order to determine the extent of survey and the location of National and Provincial
roads a range of information sources will be utilised. Table 1.1 below schedules,
which of the following sources of data are available for the 18 provinces;
1. Hard copy of Road Origin – Destination Form for all Road Classifications
within each Province. Information includes unique identifier (as per section
1.2), approximate length, start description and end description.
2. Hard copy GIS generated maps based on UXO base maps displaying National
and Provincial roads and unique identifiers.
3. Maps completed by DCTPC indicating all Road Classifications by colour and
road number.
4. Electronic UXO mapping data including District, Provincial and National
Boundaries and Road centre line data for all Road Classifications.
5. Electronic UXO mapping data as per item 4 above and mapping data for
Provincial and National Roads with road number.

The process described below and the above-mentioned road network information
shall be used to determine the extent of survey and unique identifier for each Road
link;
Status - Final

July 2001
1. Produce A1 map from UXO base mapping data for each Province.
2. Duplicate DCTPC produced National and Provincial road classification and
unique identifier or road number information onto maps.
3. For each road link mark on maps proposed start, end, node point, direction and
road number.
4. The maps produced by LCG shall be provided to DCTPC prior to District
survey for verification that the proposed road extent is correct.
5. Obtain DCTPC signature of authority to acknowledge extent of survey.
1.2
Adopted Location Referencing Method
Existing Unique Road Identification Number
The format of the unique road numbering system was determined during the SIDA
funded, Lao-Swedish Road Sector Project (LSRSP) 1997-2000. It is summarised
in a short report entitled “The Theory of Road Referencing System”. The
numbering convention is summarised below in Figure 1.2.
XX . XX . X . XXXX . XXX

Where:
G Road Classification (1= National, 2=Provincial)
G District Number (eg: 01=Vientiane Municipality, 02=Phongsaly …).
G Road Number (4 digit character number).
G Link suffix (3 digit character number).
Existing unique road numbers and a link number as defined by survey teams shall
be assigned to the road links at the time of field survey as per Table 1.2 and
Figure 1.2. Details of Province, District and Road Classification numbers shall be
recorded as link attributes. Roads that do not have an existing Road number shall
be allocated the next available Provincial road number.
A road “link” is defined as having homogeneous traffic flow (e.g. between major
junctions) and separated by different authorities responsibility (i.e. nodes and new
links need to be created at district and provincial boundaries). It is desirable to
keep links under 30-40km as it is easier to join links than to split them in the
future.

third link on provincial road 6303 in the Savannakhet province.
Establishment of LRP’s
The Location Reference Points (LRP's) will be established at regular intervals of
between 1.0km and 5.0km. In some instances these will be based upon the
existing km posts or, if km posts are missing, other fixed points adjacent to the
carriageway will be selected (e.g. major structures, bridges). When there are no
km posts the maximum distance between LRP's will be 5.0 km. The locations will
be identified to an accuracy of ± 2.5 m or better. The LRP's will be clearly
identified and located in a position, which is easily visible for future road
management.
LRP numbering will increase in terms of increasing km post numbers. If there are
no km posts on a road, the LRP's will be defined as increasing from the larger city
to the smaller city.

Single carriageway 1-lane roads: data will be collected in one direction,
nominally in the direction of increasing displacement, with the measurements
taken as close to the road centerline as possible.
Single carriageway, 2-lane roads: data will be collected in one direction,
nominally in the direction of increasing displacement, position in the travel
lane with measurements taken as close to the road centerline as possible.
Divided and dual carriageway roads: data will be collected in each direction
as separate links, positioned in a travel lane with measurements taken as close
to the carriageway centerline as possible. Displacements will always increase
in the same direction for both carriageways. The road naming convention will
be as detailed within Section 1.2 followed by direction Increasing or
Decreasing e.g. 01-01-1-13N-006-I.
Measurement of Road Attributes and Features
Figure 1.3 and the following terminology is used to outline the principals of
capturing information about the road network and features such as drainage and
topography that are associated with the network;
1. Continuous Linear Event is a linear event (start and end displacement) on or
adjacent to the road, which is measured continuously along a road link.
2. Continuous Point Event is a point event (start displacement) on or adjacent to
the road, which is measured continuously along a road link.
3. Uniform Section Event is a linear event on or adjacent to the road, which is
assumed to be constant between two LRP’s.
4. Point Event is an event on or adjacent to the road which applies to a point e.g.
bridge, sign, intersection or approaching moving vehicle etc.

Road Roughness
The roughness will be measured using the ROMDAS bump integrator (BI). This is
a response-type roughness meter attached to the floor of the vehicle with a cable
running from the spring loaded hub down to the axle. The BI then records the
relative movement of the vehicle floor to the suspension: i.e. the road roughness.
Each vehicle responds differently to roughness due to variations in the springs,
dampers and tyres. Each roughness survey vehicle has therefore been calibrated
against a standard - the International Roughness Index (IRI).
Further details of this procedure will be given in the Technical Report presented at
the conclusion of this project.

Visual Condition Rating
Pavement Surface Integrity Index (SII)2
The SII combines assessments of the incidence, severity and modes of distress in a
numeric score from 0 (representing no defects) to 5 (representing obstructive
defects). The SII score levels may be generally interpreted in terms of
maintenance intervention needs as shown in Table 1.5.1. The data will be
collected as uniform point events at regular 0.2 km intervals, based on the section
of road driven over.
SII Rating
Likely Maintenance Intervention
0
Excellent integrity, no maintenance required
1
Initiation of distress has occurred, some recurrent maintenance may be needed. At
very high maintenance standards preventative treatments may be applied.
2
Sufficient distress to warrant preventative maintenance resurfacing (or recurrent
maintenance under a corrective maintenance policy)
3
Resealing or resurfacing warranted under corrective policy
4
Rehabilitation including possible strengthening likely to be warranted; or recurrent
maintenance patching needed as holding treatment (bituminous pavements)
5
Reinstatement, major rehabilitation or reconstruction is necessary, possibly in
localised areas
The SII measure along with more quantifiable assessment criteria is detailed
further in Part C of this manual.
The predominant defect influencing the SII rating will also be collected at 0.2 km
intervals, referenced to the last LRP using the following codes:
Defect
Code
Predominant
Defect
Defect Description
CA
Cracking
The appearance of small shaped contiguous areas of cracking in the
carriageway, normally associated with pavement fatigue.
RV
Ravelling
The appearance of surfacing material loss in bituminous carriageways,
normally associated with insufficient or aged bitumen binder.
PT
Potholing
A hole in the pavement resulting from the loss of pavement material under
vehicles tyres.
FL
Flushing
The loss of surface texture resulting from surface binder becoming flush with
surfacing chip, normally associated with over application of bitumen, wet
pavement or heavy traffic and high temperatures.
PA
Patching
The appearance of remedial maintenance works in the carriageway, normally
associated with historical pavement failure.
DN
Disintegration
Extensive areas of seal loss (usually following ravelling) resulting in exposed
base, subbase or subgrade.

Moderate depth
Rut depth range >=15 – 30mm
High depth
Rut depth range >=30mm
Shoulder Condition
The predominant shoulder condition will be recorded for concrete or bituminous
pavement types only and logged as a uniform section attribute for each LRP
section using the classifications below. The aim is to assess shoulder for overall
performance, severity of maintenance required and identify any unwanted defects
which may affect pavement performance.

No Shoulder
No shoulder present, no shoulder that a vehicle could move onto
Drainage Condition
The predominant drainage condition will be recorded for all pavement types and
logged as a uniform section attribute using the classifications below. The aim is to
assess drainage for overall performance, severity of maintenance required and
identify any unwanted defects which may affect pavement performance.

1.11 Moving Off the Carriageway
At times it may be necessary for the survey vehicle to move significantly away
from the carriageway and continue surveying; for example when the road is under
construction or catastrophic failure has occurred making the carriageway section
undrivable.. When this occurs the displacement for moving OFF and moving ON
the pavement will be recorded. Roughness data will not be recorded when the
vehicle is off the carriageway.

Upgrades to the ROMDAS software are available from www.ROMDAS.com.
However, the release (5.3A) used in the initial survey performs all of the necessary
functions for data collection and thus it is recommended that this release is used
for future surveys.
The ROMDAS User’s Guide3 documents all of the tasks and processes required to
install and operate the ROMDAS system. In this document we have not attempted
to reproduce this information but rather reference chapters of the ROMDAS
manual and summarise key processes where appropriate.

SURVEY PROCEDURES
3.1
Overview
The survey procedures are used throughout the duration of the survey. Their
purpose is to ensure consistency in survey measurements. Specific details of
the data to be collected are contained in Part C of this document.
3.2
ROMDAS Road Identification Number
Overview
The ROMDAS Road Identification numbering system is a temporary
numbering system that has been developed for ROMDAS survey’s being
performed by multiple teams. Post processing of the Road Identification
numbers will establish a 4-digit road number, 3-digit link number and 2-digit
section number.
Section 1.2 of Part A details the existing GOL Road Referencing system.
ROMDAS data will be manipulated during the post-processing procedures to
align with the adopted referencing convention.
National Road Identification Number Allocation
The road identification number entered in ROMDAS for a National Road Link
survey shall be in the format of RRRTL as follows;
1. Road number as defined by MCTPC (RRR, 3 digit number)
2. Team number as defined by MW/LCG (T, 1 character, ABC or D)
3. Link number as defined by MW/LCG (L, 1 character, ABCD…..)
Link number shall be a sequential alphabetical character relative to road
number and survey team.
Number entered into ROMDAS shall be in the format of 13NAA. This
number is the first link of road 13N to be performed by Team A, the next link
survey number for road 13N shall be 13NAB.
Provincial Road Identification Number Allocation
The road identification number entered in ROMDAS for a Provincial Road
Link survey shall be in the format of RRRRL as follows;
1. Road number as defined by MCTPC (RRRR, 4 digit number)
2. Link number as defined by MW/LCG (L,1 character, ABCD…..)
Status - Final
B-6
July 01
Link number shall be a sequential alphabetical character relative to road
number.
Number entered into ROMDAS shall be in the format of 6303A. This number
is the first link of road 6303, the next link survey number for road 6303 shall
be 6303B.
Divided or Dual Carriageway Road Number Allocation
The road identification number entered in ROMDAS for National or
Provincial road links that are surveyed in an increasing and decreasing
direction shall be in the format as described above followed by an single
character indicating Increasing (I) or decreasing (D) direction.
3.3
Locating Administrative Boundaries
Overview
Administrative boundaries shall be the start of a link and a node. The known
location of administrative boundaries (National, Provincial and District) varies
between various information sources.
Process to Locate Administrative Boundary
To determine an appropriate location of these points in the field the process
described below shall be used.
1. Definable geographical co-ordinates for roads intersecting administrative
(National, Provincial, and District) boundaries shall be derived from
mapping data provided by UXO.
2. When a link is to be survey which ends at an administrative boundary the
co-ordinates shall be entered into the GPS receiver as a waypoint1 and set
to indicate the proximity when within a radius of 1km.
3. Survey team shall identify physical location with assistance from DCTPC
staff in survey vehicle.
4. When there is a conflict between the location of a district boundary derived
from the UXO maps and local signage/knowledge, the local signage should
be taken as the “true” boundary.
3.4
Survey Planning
Provincial Planning
Prior to mobilisation from Vientiane, the survey team leaders will confirm the
extent of their road survey and where nodes will be established on oads that
cross over into adjacent teams survey areas.

Appendix D describes the GARMIN 12XL GPS receiver in more detail.
Status - Final
B-7
July 01
Where a link is defined at a location (node) that is a not easily identifiable in
the field then one of the survey team(s) shall survey beyond this point to an
identifiable node point which the adjoining team(s) shall survey from or too.
District Planning
Prior to surveying roads in each district, the proposed extent of survey for
within the district shall be approved by the local DCTPC. This shall include
the nightly rest locations as well as possible intermediate stops in case of
problems.
Daily Planning
Each day survey objectives should be planned, including confirming the
location and extent of from the UXO maps.
Link Planning
Roads shall be divided into smaller parts called links. The links will start and
end at major junctions where the traffic flow changes and at administrative
boundaries2. For practical purposes, links should be kept below 30-40km in
length.
Road links shall be planned from the available information prior to survey
team mobilisation, the proposed start, end and link number shall be marked on
the Provincial maps in pencil. At completion of the link survey these details
shall be validated and remarked in pen.
3.5
Team Member Roles
Team Leader
The Team Leader is responsible for the overall survey operations and Survey
Quality Management as detailed throughout this document. The team leader
can perform any function within the Team, however it is preferable that the

Link Data Validation
At the immediate completion of surveying each road link a Microsoft Access
Runtime Link Data Validation interface shall be used to interrogate the data
and indicate any data deficiencies.
Should data deficiencies be returned these should be rectified immediately, if
the deficiencies can not rectified they shall be logged on Form 06 and
performed at the end of the day or refereed to senior project staff.
Section 4.0 details how the Microsoft Access Runtime Link Data Validation
interface operates and recommended error actions.
3.10 Repeat Surveys
Overview
The objective of the repeat survey is to ensure each batch of data throughout
the duration of the survey is complete and accurate, comparison of the data
sets shall check for;
G
G
Completeness, each batch of data meets the data specification.
Accuracy, each batch of data has consistent attribute and condition
assessment data.
The first repeat surveys shall be performed within 5 days of each teams
departure from Vientiane. Upon achieving the data acceptance criteria
further repeat surveys shall be performed approximately every alternative
Friday by each team. Form 05 shall be completed for repeat surveys.
The repeat survey data shall be compared against the original survey data
through the Microsoft Access Runtime Repeat Survey interface. This
interface shall undertake link data validation as per Sections 3.9 and 4.0 and
check for data completeness and accuracy as specified in Table 3.10.2.
Repeat Survey Batch Number
The teams groups of repeat surveys shall be allocated a Batch Number. The
Batch Number shall consist of the allocated Survey Team Code and a
Sequential Number. This batch number shall facilitate the grouping of the
original survey data by survey date since the last repeat survey and date of
current repeat survey as shown in Table 3.10.1.

Provincial Roads shall have the original file name preceded by a B, e.g.
for original survey file 6303A the file name shall be B6303A.
National Roads shall have the original file name preceded by a B, e.g. for
original survey file 13NAC the file name shall be B13NAC.
The data files shall be stored in the respective ROMDAS survey date
directories.
Repeat Survey Procedures
Each team shall perform a repeat survey on a segment of road containing at
least 3 LRP’s and being greater than 3.0 km in length. The section must have
been surveyed at least 7 days previously. The road sections are to be complete
and continuos LRP’s lengths.
Repeat surveys shall only be performed on Road Links where the Road link
meets the following criteria;
G
G
G
G
G
G
Must be sealed.
Data validation process of the original returned no errors that required an
action logged to Form 06.
Contain no construction sites.
Contain no impassable sections of road.
Contain no movement on or off the pavement due to physical conditions.
Contain no section of road which requires vehicle speed <=10 km/hr.
Sites for repeat surveys should be considered at the completion of the original
road link survey and marked on the maps for future reference.
Data Acceptance Criteria
Tolerance criteria will be applied to each batch of original survey data. Should
the data types fail the acceptable limits, further repeat surveys shall be
performed until the offending data types meet the acceptable limit.
For example:
If the Tolerance Criteria for the recording of LRP displacements is “position
within ±10m” and the Acceptance Limit is “0”, then this means that the
location of all LRP’s recorded during the repeat survey must be within 10m of
those recorded during the original survey.
If data is found to be consistently in error for data batches then the parameters
of these data deficiencies shall be established for post processing and recorded
on Form 06 and actioned by senior project staff. The team leader shall define
and document these parameters and validate subsequent data processing.

3.11 Dealing with Specific Field Situations
Unfixed GPS Signal at Link Nodes
If GPS signal can not be fixed in ROMAS at the beginning of a road link
survey the following alternatives can be performed.
1. Manually record details of GPS location on Form 03, indicate this as a
manual entry by circling the attributes as shown on the example Form 03.
2. Record on Form 06 the details time and why signal may not have been
fixed, e.g. dense vegetation, mountainous terrain, inadequate satellites
(<=2).
3. If inadequate satellites, log action as return to site at different time to
collect geo co-ordinate data

Interrupting Surveys
To improve the efficiency of the survey programme it is often necessary to
interrupt what should be a continuous run to measure roads running off from
the primary survey route or if a road is impassable. Examples of this are
shown as per Figures 3.11.1 and 3.11.2. The procedure to follow is:
Run 2
Run 3
LRP or Roadside Feature
Run 1
Continuation of Run 1

The operators shall terminate the main survey at an LRP or other roadside
feature that will be easy to return to (Run 1). It is generally recommended
that this be past the point where the other surveys are to commence.
They may then execute the other surveys (Run 2 and Run 3).
They shall returning to where they ended the previous survey they enter
the same Road ID as was used previously. They will then be given the
option to continue the previous run. The data collection will be started
where they left off and, once processed, both components of Run 1 will be
integrated.
Unusual Events
If something arises during the survey that will influence the survey results
press the F8 key to log it in ROMDAS as an Unusual Event. Also, record
details of chainage, description and recommended action on the Form 06.
3.12 Digital Camera Operation
Digital photos are to be taken of all “nodes” (photos of intermediate LRP’s are
not required). The photo is to be taken from beside the driver’s door looking
toward the section of road to be surveyed.
Taking the Photo
Photos are stored on the internal memory card that holds 31 photos when the
camera settings are configured as per Part A.

After selecting OK, the files will transfer to the daily storage directory and
then be deleted from the memory card. The transfer rate will be reported
but could take up to 5 minutes.
5. In the event that more than 31 photos are transferred in a single day then a
second image album will need to be created by placing a “B” after the
current date (e.g.: 12 February 2001B). This will ensure the first series of
photos downloaded are not overwritten.
File Renaming
At completion of successful data transfer update the photo file names to
represent the road link. If a side node photo has be taken rename in the format
of road link followed by side e.g. 6303r.jpg.

LRP Photo Numbers
LRP photo numbers are to be numbered sequentially for each day’s survey.
The digital camera will assign a sequential number of image 1, image 2 etc.
These image numbers are to be entered into ROMDAS for the LRP photo
number. If a side node photograph is taken the details shall be recorded
manually on Form 03.
The photo number for intermediate
LRP’s in ROMDAS shall be set to
null.
This is done by clearing
(backspacing or delete) the provided number until the cell is blank. After the
first photo has been assigned to null selecting entering in ROMDAS will
confirm the photo number already exists, choose Accept as shown above.
The photo name will be recorded in ROMDAS in the format of date
(yymmdd), and sequential photo number of day (xyz) e.g. 010212-015.jpg.
1.3
Digital Photographs
At least one digital photograph shall be taken at each node (i.e. first LRP in a
link). The photograph(s) shall be taken on the road centre line looking in the
increasing direction. The bottom of the photograph shall be the zero point of
the road link. Figure 1.3.1 shows an example increasing node photograph.
If the node is not an easily identifiable point when looking from the increasing
direction photograph then an additional photo identifying a feature on either
side shall also be taken and side photograph details recorded on Form 03.

CONDITION RATING SURVEY
2.1
General
The condition rating survey shall be undertaken from the moving vehicle. The
pavement condition rating has been based on the 'Surface Integrity Index'
(SII). This is an index presented in Paterson (1993)2. The condition rating
will evaluate surfaced pavements only for the incidence and severity of
pavement surface distresses, the predominant defect and a rutting
classification. The overall performance of the road shoulder and side drainage
is also to be assessed for each road link.
2.2
Survey Procedure
Pavement Condition Rating
The procedure for performing the pavement condition rating survey is:
G
G
The observer, from the moving vehicle, will evaluate the sealed
carriageway and determine scores representing the incidence and severity
of defects.
The observer will record the SII score, predominant defect and rutting
depth band for the previous 200m of pavement via the pre-programmed
keyboard.
Drainage and Shoulder Condition Rating
The procedure for performing the drainage and shoulder condition rating
survey is:
G
G
2.3
The observer, from the moving vehicle shall, evaluate the shoulder and
drainage for overall performance, severity of maintenance required and
identify any unwanted defects which may affect pavement performance.
Upon reaching an LRP the observer will record the drainage and shoulder
condition classifications via the pre-programmed keyboard.
Surface Integrity Index Pavement Distress Score
The SII combines assessments of the incidence, severity and modes of distress
in a numeric score from 0 (representing no defects) to 5 (representing
obstructive defects). Defects to be considered as part of SII evaluation for
bituminous roads are as shown in Table 2.3.1.

INTRODUCTION
1.1
Background
General
Office data management is the process of managing the ROMDAS survey data
generated by survey teams. The subsequent manipulation of this data into a
format suitable for delivery to the MCTPC is discussed in the final project
report “Data Handover – Final Report” (MW801/002254-01-C).
ROMDAS data management refers to the management of ROMDAS
generated data only. Management of data and information pertaining to digital
images, 35mm film images and Hi8 video images are covered in separate
items within this document.
Data office management cannot be completed successfully with out reliable
details of the data generated by the survey teams. The details of the data
generated by the survey teams will be recorded on Form 04 Data Quality
Management and must be provided at the time of data transfer to the Lao
Consulting Group Head Office (LCG HO).
Details of Form 04 are contained in Part B Sections 2.0 and 4.0 of this

by three methods as follows;
G
G
G
Data transferred to LCG sever via modem from ROMDAS computer.
Data transferred from ROMDAS computer to LCG server or intermediate
computer via FastLynx software and cable.
Data transferred from back-up floppy disk to LCG server or intermediate
computer.
Modem to Server Data Transfer
Details of modem to server data transfer are contained in Part B Section 4.4.
On occasions data received by this method renames or truncates the file names
and incorrectly adjusts the filename extension. If this occurs the file(s) should
be temporarily renamed to allow uncompressing of data and to determine the
daily date directory.
FastLynk Data Transfer (Version 3.1)
FastLynx is a program that copies files and directories between two computers
that are connected by a serial cable, parallel cable, a local area network
(LAN), or the Internet.
FastLynx has been installed on all project computers, ROMDAS computers,
and the LCG server. Data is transferred by connecting computers using a
parallel cable.
For details on how to operate the FastLynx version 3.1 software refer to Part D
Section 5.0.
Back-up Floppy Disk Data Transfer
Data transfer from floppy disk to LCG server or intermediate computer is
performed by using windows explorer to copy and paste the daily zipped files.

BASIC FASTLYNX OPERATING INSTRUCTIONS
When FastLynx starts up, the left side of the FastLynx window shows a
directory listing of files on the local computer. What is shown on the right
side of the window depends on whether FastLynx is in local or remote mode
(this setting can be changed from the Connection menu). When FastLynx is
first installed, it initially defaults to remote mode. Remote mode means that
FastLynx is going to try to connect to another computer and allow you to
transfer files between the two computers. Local mode means that FastLynx
allows you to display two different directories that are on the local computer
and transfer files between them.
When in local mode, the right side of the window always shows a directory
listing from the local computer. Initially, the directory shown is the same one
that is shown on the left side. To transfer files, you must change the directory
shown (by using the Change Directory command from the File menu) on each
side to the directories that you want to transfer between.
When in remote mode, the right side will show a directory listing from the
remote computer if a connection has already been established. If a connection
has not been established, the right side will show the types of connections that
FastLynx is trying to make. To successfully connect, the
Remote computer must be set to ‘Listen as server’, the computer you are at
must be set to ‘Connect as client’, and both computers must have the
connection types selected with appropriate parameters. When connecting via
serial or parallel, the appropriate cable must be plugged into both computers
on the specified ports.
Once a connection is established, both sides of the FastLynx window will
show a directory listing.
To copy files, select them with the mouse and drag them to the opposite side.
Alternatively, you can select the desired files and then press the Copy or Move
button, or choose the Copy or Move option from the File menu.
For commands that involving transferring files (Copy or Move), the direction
of transfer is determined by which directory listing is selected. The selected
directory is the source, and the non-selected directory is the destination.
Clicking inside the directory listing with the mouse will select that directory.
You may also toggle the current directory selection by using the Tab key. The
selected directory listing (the source) will have its title bar highlighted, and
will indicate the number of files in the directory that are selected. The black
arrow always points away from the source directory and points toward the
destination directory. The non-selected directory will show the amount of free
space available in its title bar.
Status - Final

July 01
For commands that operate on files without transferring them (rename, delete,
view), the command will operate on the currently selected file or files. You
can select files in either directory listing.
