Can anyone tell me what prefix it uses and where the files are actually stored? I'm looking for the drive_c folder it installed into
The only mapping I found between a manually added .exe and prefix is in the shortcuts.vdf file (somewhere in ~/.steam/). You need to read the file with a hex editor. It's the 32bit unsigned int after the "appid" identifier.
So yeah... probably easier to follow Ehvis advice and search for the folder or list the compatdir contents by date and open the latest created one.
If you don't know it you can simply grep for the name of the game in the .acf files (one level above the compatdir directory). The match will have the Steam AppID in the filename.
Still, I would like to see an "Open Prefix in file browser" button in the Steam client!
What's weird about shortcuts.vdf is that the appids match those used for the grid images, but not for the directory names of the screenshot directories in .steam/steam/userdata/USERID/760/remote/APPID/screenshots
Non-Steam games will always create prefix in your home dir by default no matter where you install the game itself. And yes, Steam is notoriously terrible at deleting these dirs so you'll definitely have to do some manual cleanup.
Example output:
$ ./compatcheck.sh
Non-Steam apps - Note that these compat dirs may no longer exist.
Default location: /home/panther/.steam/steam/steamapps/compatdata/
