I've tested it 2 weeks ago - it worked far, far from perfect - ideed, far from good! I combine usually 10 - 50 inf files(drivers for the same class, e.g. chipsets, nic etc.) into one subdirectory(audio in 5 subdir beause of filename conflict). With method 1 it works perfectly. But with this AutoIt method, it took more time to register all the inf file on the cd than the method 1 to copy all the files from cd onto hdd, much worse, 20%-30% of inf file ware not accepted - so As long as it not works perfectly, it is useless - It takes also more time for the Installation.
