# Import and export file formats

Predefined import and export file formats are defined using XSLT stylesheet (*.xsl) definition files. They are typically located in the Trimble Data\System Files folder.

The predefined stylesheet definitions are provided in English. Translated stylesheet files are typically 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>

You can import and export data using the predefined file formats, or you can create your own formats.
