Any Easy Way to Tell if a File is .dxt or .bmp?

[Chuck_B 2]

I want to convert all my WOAI paints and other AI, and probably some of my custom downloaded paints, and I was wondering if there is an easy way to tell the difference between a regular 16 or 32 bit .bmp and .dxt. There's no indication in the Properties section when I right click on the file. I already have a batch file for texture conversion, but I was thinking there's no need converting if they've already been done -- and with my luck I'd probably do more harm than good. :-). I've done a search here and on Google and found several posts about how to convert files, but I can't find an actual answer on how to tell if a file is already a dxt.Thank you!

Are you looking for a way to tell visually or programmaticaly? If you just need a visual way to tell try opening the texture folder in Windows Explorer and view by thumbnail. If you see a thumbnail preview it's a regular bitmap, otherwise probably DXT. That's been my experience anyway.

If that's the way it always works, that way would be just fine! Thanks George. I'm using XP, by the way, just in case it matters.

ChuckHave you heard of the DXTbmp program?.This is a really good free texture manipulator that will also tell you exactly what format a file is when you drag it into the program.It is VERY useful and much more comprehensive than the usual simple texture conversion programs available.cheers Andy

Hi, Andy! Yes, I use it all the time. What I'm trying to accomplish is a maximization of system performance and I want to quickly see how many of my AI textures are in .bmp format (slow) and how many are in .dxt (not so slow) without having to open each file.If George's technique is correct, that'll do. Otherwise, DXTbmp is definitely the way to go.Thanks -- hope you had a nice holiday!

Also try searching the aircraft folder for file sizes. A DXT without mips will be 1MB, one with slightly more. If you start searching for files say larger than 2MB, you'll find plenty of regular bmp's to convert.

Another great idea. Thanks, guys.

There is also a freeware viewer called xnview which will display dxt format. It has its own browser and if you display "details"view you can sort on file type and it will sort out all the dxt format for you.http://pagesperso-orange.fr/pierre.g/xnview/endownload.htmlscott s..
