Hi, Here is the update on this issue. If MAKECAB Directive is given via .ddf file like one given for driver.cab MAKECAB /F UC.DDF - Works fine and after windows setup, installed file date stamp is same as original whereas any file created without .DDF directive like on below MAKECAB /D CompressionMemory=%COMPMEM% /D CompressionType=LZX "%ALTSRCDIRS%HFEXPERT\STORAGE\%%I" /L SOURCESS\I386 >NUL gives wrong date stamp. - after windows setup, installed file date stamp is current date and not original file date Even with files from original CABSDK (1997 version), error persists. But here if expand/extract directly to a folder it shows original file date, but after windows setup, it shows current date instead of original file date. Hope above points will give some clue. Attached is the directory listing of Windows 2000 driver folder after windows installation. Marked files are the files added via HFExpert - Drivers / Storage folders. same for HFExplert - Win folder.
