# Data folders and files

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:

- Windows: C:\ProgramData\Trimble\Trimble Access\Trimble Data
- Android: <Device name>\Trimble Data

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

- If you cannot see the Trimble Data folder on an Android device, in File Explorer tap and select [Show internal storage]. Then in File Explorer tap and select the device name. The Trimble Data folder appears in the list of folders on the device.
- To see the System Files folder on a Windows device, 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 file types are stored in the <project> folder:

File type | File extension
--- | ---
Job | .job
JobXML | .jxl
CSV (comma delimited) | .csv
TXT (comma delimited) | .txt
DTM (Digital Terrain Model) | .dtm
TTM (Triangulated Terrain Model) | .ttm
IFC (Industry Foundation Classes) | .ifc, ifczip
TAP (Trimble Additional Properties)* (For IFC file of same name when station interval settings are configured) | .tap
TrimBIM (Trimble BIM) | .trb
DWG (Drawing) | .dwg
NWD (NavisWorks Drawing) | .nwd
DXF (Drawing Exchange Format) | .dxf
ESRI Shapefiles | .shp
Georeferenced map file world files | .ifcw, .dwgw, .dxfw, trbw
Georeferenced background images (Along with georeferenced world file of same name, for example .wld, .pgw .pngw) | .tif, .bmp, .jpg, .png
RXL (Trimble Road or alignment) | .rxl
LandXML | .xml
GENIO road | .crd .inp .mos
12d Model files | .12da
Surpac | .str
TXL (Trimble Tunnel) | .txl

- Where possible, Trimble recommends using the job (.job) file created in Trimble Access in preference to the equivalent JobXML or JXL (.jxl) file created in Trimble Business Center. For more information, see Using existing jobs with the latest version of Trimble Access.
- All .xml files except the GNSSCorrectionSource.xml and GNSSInternetSource.xml are stored in the <project> folder. The GNSSCorrectionSource.xml and GNSSInternetSource.xml files must be stored in the System Files folder.
- Georeferenced map file world files are created when you use the Georeference map Cogo function in Trimble Access and contain information about the transformation.
- Georeferenced background image files cannot be created in Trimble Access. GeoTIFF files do not require a world file. JPG files must be in 24-bit color; pure grayscale JPG files are not supported.
- 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, unless you select a different export folder.
- The .wfs Files folder appears in the <project> folder when you connect to a web feature service and then save the features as a .wfs file.
- A TAP file appears in the <project> folder when you configure station interval settings for an IFC file. For more information, see Stations available for stakeout.

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.

Files created while working in the job are stored in the <job name> Files folder. These include images, point clouds, and GNSS data files:

File type | File extension | Subfolder
--- | --- | ---
GNSS data | .t01, .t02, .t04 |
Images | .jpg |
VX or S series scans | .tsf |
SX10 or SX12 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 or SX12 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 or SX12 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 drive, 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
SnakeGrid coordinate system files | .dat
UK National Grid files | .pgf
Broadcast RTCM transformation files | .rtd
Antenna files | .ini
GNSSCorrectionSource file | .xml
GNSSInternetSource file | .xml
Cadastral tolerances file | .xml
Custom Import file definitions | .ixl
XSLT Custom 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 tile service configuration file | .wmts
Echo sounder definition file | .esd
Utility locator definition file | .uld

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

The Cache folder appears in the System files folder when DWG, IFC, or NWD files are loaded in Trimble Access. Caching DWG, IFC, and NWD files on the controller enables faster reloading of these 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.

Language, sound, and help files

Language files (.lng), sound files (.wav) and help files are stored in the appropriate language folder.

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

- Windows: C:\Program Files\Trimble\General Survey\Languages\<language>
- Android: <Device name>\Trimble Data\Languages\<language>
