Oh, Steam! You're right null!!! And I would add the steamdata.ini file (the main file for steam in gameex), that is in DATA folder. If you added a lot of non-steam games with custom descriptions, artwork, trailers, etc like me, this is definitely a file to backup. The steamdata.ini follows this scheme: [AppID_XXXXX] (where XXXXX is, indeed, the Steam ID for a particular game] installdir= gamename= exe= description= genre= year= developer= If you add custom trailers, screenshots, etc in the corresponding folders in MEDIA\STEAM, assigning them the same name as the AppID, you can populate the Steam menu in GameEx with a complete set of information & artwork even with non-steam games. EDIT: when I speak about an AppID for non-steam games, I mean that when you add a non-steam game in steam, a random ID is generated and saved in shortcuts.vdf in steam folder. GameEx will catch that game, provided that you launch it at least once.
