FS and GpsDump files are in general standard formats used by other software. XML files are used as much as possible, as they are human-readable, and easy to work with. You can make manual changes to the files if you need to.

Waypoint files

Note that files with name of .WPT can be different formats and not all work with FS. both OziExplorer, CompeGPS, and GPSDump/FS uses the same .WPT name on the file, but they are in fact different types of files. FS can only read waypoint files in Geographical format. If you have a .WPT file from OziExplorer or CompeGPS you need to convert it to Geographical before opening in FS. Use the following procedure;

1. Open the file in GPSDump - File, Open Wpts.
2. Select all waypoints (Ctrl-A)
3. Save as a Geo WPT file - File, Save Wpts. As, Select Geographical (WPT), give it a new name.
4. Open this new WPT file in FS.

You can see the change in the file if you open it in Notepad. This is the header of a OziExplorer .WPT file;

GPSDump can read many different formats of Waypoint files, and you can also use ​GpsBabel software to convert between different formats, or read the Waypoints directly from a GPS device in GpsDump.

Tracklog files

FS reads tracklogs in XML format compatible with Google Maps/Earth?. The files are usually called .KML

IGC tracklogs can also be read and used, and GPSDump will read nad write IGC files.

FSDB files

The FS database file is called .fsdb, and contains the task, participants, and scoring information. This is an XML file, and can only be read by FS. You can make manual changes to this file if needed, but remember that rescoring a task might overwrite your changes.
