[Gimp-user] No Filenames Recognized By Gimp

[Daniel Banks <d banks phinedezign com>]

Gimp will not open any file type other than it's own native format. It 
will not recognize and open a .JPG or .GIF, for example. Also, it will 
not allow me to export a .XCF file with to any other extension/filetype. 
There are no filename extensions listed in the File Type box under By 
Extension. It is blank.  I have completely uninstalled the program, 
including the .gimp-2.8 folderin my Profile folder. I have done this 
several times with no change in the behavior. I even tried replacing my 
own plug-ins folder with someone else's plug-ins folder who's Gimp 
install was working properly.

This issue began with the upgrade to 2.8. This is on a Windows 7 64-bit 
system. Can someone please help me figure this out so that I can get 
Gimp working properly again? Thank you!!
