Trimble data folders

All data used by the Trimble Access software must be stored in the appropriate folder in the Trimble Data folder.

The location of the folder depends on the controller operating system:

On a Windows device:C:\ProgramData\Trimble\Trimble Access\Trimble Data
On an Android device: <Device name>\Internal shared storage\Trimble Data

To view the Trimble Data folder from the Trimble Access software, tap and select Job data / File Explorer.

To see the System Files folder, select View at the top of the File Explorer window and select the Hidden items check box.
The Projects folder is created in the Trimble Data folder the first time you run the Trimble Access application.

To pin the Trimble Data folder to your Favorites list in Windows Explorer, select File explorer from the Job data menu in Trimble Access. In Windows Explorer, scroll up to the Favorites list at the top of the left pane. Right click Favorites and select Add current location to Favorites.

Project folders

Each project is stored in its own folder in the Trimble Data\Projects folder.

Project files are stored in the appropriate <project> folder and can be used by any job in that project. Project files are typically map files, alignments, or control point files.

The following files are stored in the <project> folder:

File type	File extension
Job files	.job
JobXML files	.jxl
Comma Delimited (CSV) files	.csv
Comma Delimited (TXT) files	.txt
Digital Terrain Model files	.dtm
Triangulated Terrain Model files	.ttm
IFC (Industry Foundation Classes) files	.ifc
DXF (Drawing Exchange Format)	.dxf
ESRI Shapefiles	.shp
Georeferenced image files*	.tif, .bmp, .jpg, .png
Trimble road or alignment files	.rxl
LandXML files	.xml
GENIO road files	.crd .inp .mos
12D Model files (Roads only)**	.12da
Surpac files	.str
Tunnel file	.txl

To be shown in the map in Trimble Access, georeferenced image files must have an associated world file with the same name. Supported file extensions for world files include .wld, .tifw, .bpw, .jgw and .pgw. GeoTIFF files do not require a world file.
JPG files must be in 24-bit color; pure grayscale JPG files are not supported.
To use a .12da file, you must use the Trimble Access Roads software to create a GENIO .mos file that contains models extracted from the .12da file.

Htm reports (.htm) and comma delimited files (.csv) that are created when you export data using the Export function in the Jobs screen are also stored in the <project> folder.

Job folders

Each job is stored as a .job file in the appropriate <project> folder.

If required, you can store jobs in folders in the <project> folder. For Trimble Access to be able to use the job, the combined length of the project folder name and folder names must not exceed 100 characters. The name of the job is not included in the 100-character limit.

To move a job to a different folder, use the Copy job function in Trimble Access to copy the job and all linked files to the new folder and then delete the original job. See To copy job files.

To avoid data synchronization issues, do not move jobs downloaded from Trimble Connect to a different folder.

Each job has a <job name> Files folder which contains files such as image or GNSS data files that are created as work is done on the job.

The following files are stored in the <job name> Files folder:

File type	File extension	Subfolder
GNSS data	.t01, .t02, .t04
Images	.jpg
VX or S series scans	.tsf
SX10 scans	.rwcx	<project>\<job name> Files\SdeDatabase.rwi
Original images	.jpg	<project>\<job name> Files\Original Files

When a scan point measured using a Trimble SX10 scanning total station is used in the job, for example in a Cogo calculation, a point is created in the job at the same position as the scan point.

Auto‑generated folders are created as required, inside the <job name> Files folder:

<project>\<job name> Files\Original Files is created when you draw on or annotate an image file. The original, unedited image is copied to the Original Files folder.
<project>\<job name> Files\SdeDatabase.rwi is created to store .rwcx scan files if you scan using a Trimble SX10 scanning total station.

To easily copy jobs and associated files from one folder to another, or from one controller to another using an external drive such as a USB stick, tap Copy in the Jobs screen.

System files folder

All system type files are stored in the Trimble Data\System Files folder. System files are files that can be used by any project or job, such as survey styles, coordinate system files, and feature library files.

System files cannot be accessed if they reside in another folder.

The following files must be stored in the System Files folder:

File type	File extension
Feature Library files (TBC)	.fxl
Survey Style files	.sty
Geoid Grid files	.ggf
Combined Datum Grid files	.cdg
Configuration	.cfg
Projection grid files	.pjg
Shift grid files	.sgf
UK National Grid files	.pgf
Broadcast RTCM transformation files	.rtd
Antenna files	.dat
GNSS Contacts file	.xml
Custom ASCII Import file definitions	.ixl
XSLT Custom ASCII Export Stylesheet files	.xsl
XLST Custom Stakeout Stylesheet files	.sss
Measure Codes Database files	.mcd
Coordinate System Database files	.csd
Web map service configuration file	.wms

Web map service (.wms) files are created when a WMS is added in the New web map service screen. They can be copied between projects and controllers.

The Cache folder appears in the System files folder when IFC files are loaded in Trimble Access. Caching IFC files on the controller enables faster reloading of IFC files.

Stakeout stylesheet files (.sss) and Custom Export stylesheet files (.xsl) can be located in the language folder or System Files. Translated Stakeout stylesheet files and translated Custom Export stylesheet files are typically stored in the appropriate language folder.
