Different games you have purchased in Game Pass through the Xbox app keep their save files in different structures. This fact makes moving that save file from platform to platform difficult.
For example, if you play Destiny 2 on Xbox but then want to play on Steam - you would likely need to start over. PC Game Pass Save Converters' goal is to streamline this process, making your save games more portable.
PC Game Pass Save Converter looks for games in your WGS folder and then matches it up with its growing library, then will attempt to convert the save game file to the appropriate format. If your game is not found in this library, you will be prompted to select the location manually when a package is selected.
It is strongly recommended that you back up both save file folders (WGS and whatever other location) before using this application.
