I guess this should go here.

Anyway I have Oblivion GOTY installed with mods and It is running fine. I have noticed after I installed Fallout 3 GOTY that all of my Oblivion .bsa files in the Data folder have the Fallout icon next to them instead of the Oblivion icon. It does not seem to hurt anything but I thought it was odd. Has this happened to anyone else or is it just one of the weird things that happens with Bethesda files? The games are in their own folders (C:\Games\Oblivion) (C:\Games\Fallout3). I have Windows 7 Home Premium as the OS. Any insight would be appreciated.

Don't worry about it. The game will still work.

They used the same file extensions for all the games on the same game engine. (morrowind, oblivion, FO3, FONV) so, whichever one is installed LAST, is the icon used for files of that type.
