There are many driver backup programs, but I haven't found any totally free / working one for my usage. I would like to code my own and share it with you guys, but I don't know where to start.

The main thing I first need is the best method for seeking the right driver files. I know that there are users who knows the method of where to check these files, so if you please can share it.

Have you tried these both totally free, well siginet asks for a donation.

WMI queries can return the name of the INF file. Then you can read the INF file to get the needed driver files, find them and back them up.

Thanks for help IcemanND. Actually I found one that worked like a charm and the source code is also included.

I have tested your program simultaneous times, but it always gives the error message that I have put in your thread.
