DirtDevil Posted March 19, 2004 Share Posted March 19, 2004 I'm about to experiment with some drivers and wonder what is in those catalogue-files. Is there some way to open it? To have look on what information is stored in it? How driver-files are managed or whatever...So, I'd like to know how these catalogues work. Can someone help me?Thanks in advance Link to comment Share on other sites More sharing options...
Alanoll Posted March 19, 2004 Share Posted March 19, 2004 you can't open them.catalogue files are the certificates to the drivers that say they've been signed and verified and everything else. Link to comment Share on other sites More sharing options...

Ausmith1 Posted March 19, 2004 Share Posted March 19, 2004 They are the Verisign digital signatures for the driver files.I'm not sure why they don't just sign the driver file itself, it might have something to do with performance or maybe it's because Microsoft have to sign the file. I think that you need the source to sign a compiled executable like a driver, and I'm sure that most driver writers don't want MS getting their hands on their source...You can right click on a .cat file and view its information in the "Digital Signatures" tab.
