What is DXT Format?

[shev]

I wanna make some edition for the red star roundel in two wings of the Russian Air Force, but when I used CDDS browser and chose the file name RUS-STAR-ZNAK.TGA (WorldTexturesTGA.cdds), it reported that "Invalid DXT Format". So i'am totally lost, can anyone help me, really appreciate!!!! ^^
Did I choose the right file? If i want to make some diffirent to the soviet red stars, what do I have to do?

Change the extension of the file : it should be .dds

He means when trying to extract it he gets that error. Unfortunately there's not much to do, unless you got a buddy with one lying around, as that should be an old Flanker 2.51 texture. If you're meaning to edit the ones that are on most of the Russian A/C then the file you're looking for is "nomera.tga" and that can be found at my site at the link below.
