How to fix "failed to create save" or "failed to create path"

Errors like "failed to create save" or "can't write config file" in Jedi Academy or Jedi Outcast usually occur due to permissions issues on your operating system.

If you are on Windows, this is most likely due to OneDrive taking over your Documents folder if you are using any OpenJK-based mod like OpenJK, JAEnhanced, EternalJK, etc. OneDrive by default sets that folder as a cloud folder rather than a local one, which can create permissions issues with games.

You can simply unlink OneDrive from that folder through the OneDrive settings (Settings, Sync and backup, Manage backup)

Another option is to uninstall OneDrive entirely if you don't use it, or at least sign out of it.

You can also set the game to use the Jedi Academy folder instead, which is be best solution, in my opinion.
