Steam game

reinstall steam, then open steam then it should show if any games are still in the steam location, then uninstall those games and then remove steam.

are you sure it is steam that took the space, did you download any windows store or xbox app games.

add the game into steam client as a non steam game and it should work using steams controller support.

To play Steam games, you must use Steam. You can't play Steam games through the Xbox app.

I believe the TC is trying to add The Windows App version of FH5 to the Steam launcher as a none steam game. This isn't possible.

Unfortunately due to the DRM the Xbox App installed games still use, it's not possible to add these games to your Steam launcher as none steam games.

GoG Galaxy does allow you to add games from any PC launcher, including the games from the Windows Xbox App.

If you want to stream the Xbox App version of FH5 via steam, you should still be able to by this by launching Steam in Big Picture mode and then minimising to the desktop.

On the other hand if your question was about transferring the game from Windows to Steam then that's not possible. If you want to own FH5 on Steam, you'll need to buy the Steam version.

It depends are you downloading or playing fortnite via steam or xbox games for windows 10 and above

If steam you MUST ask steam for help due to the drivers in steam

If xbox games for windows sony does not support xbox games for windows or windows

It only supports steam and ps games on steam

However you have to get support from ds4win who writes drivers for Sony controllers upto the dual sense controllers
