on some directories I found dxva_sig.txt

from which program is this file?

A file with the .txt extension is a notepad file.

Notepad is located under Start > All Programs > Accessories > Notepad.

If you want to know what app made that file, you'll have to tell me where the file is located, and show me its contents.

No I mean which program has created this file?

I haven't created by my one. So I think this could be a job for CCleaner?

Open up that file in Notepad, and then copy and paste its contents here. That will probably give me, or anyone else for that matter, a clue as to what it is and what made it.

Also, tell me where it is located on your hard disk; what is its directory? If we know what app made it, and where that app puts its files such as dxva_sig.txt, we can know what to suggest to MrG.

Media Player Classic is what creates dxva_sig.txt on my system in the folder where a *.wmv is played from. WMP however doesn't create those files on my system.
