I've got to believe MS imbeds something into their files to indicate what the file was created in.

Use LLFF to get individual bytes and do your testing. The idea is that certain files have a certain sequence of bytes somewhere close to the beginning of the file.

Thanks for the info Hilmar. I'll check out the download site. Sorry for the double-post. Didn't realize this was a problem across forums. I thought the VFP people wouldn't see the Office post and visa-versa but I guess it all depends on the user's settings in UT.
