Extract patch storage file for Windows 2000+.
Usage: PSFExtractor.exe <CABFile>
PSFExtractor.exe -v[N] <PSFFile> <description file> <destination>
You need to put CAB file alongside with its corresponding PSF file. After that you'll get a folder which contains extracted full update. You can either use it with dism /online /add-package directly or repack the files inside the folder into a CAB file.
The tool requires Windows 2000 or above.
Support any PSF file with PSM/XML description file.
