- Some Windows 11/10 updates are available as a PSFX format
It consist of cab file that contain the update manifests, and psf file that contain the raw payload files
- There are two types of this format:
PSFX v2: delta update files which require WinSxS source files
Baseless PSFX: complete update files which have no dependencies
- To use those files with DISM
/Add-Packagecommand, it is required to extract (generate) the actual payload files first
Afterward, you can use the extracted folder path with DISM, or compress the folder into a full cab file or esd file
- The provided scripts automate the process and repackage the psf/cab files into full file
-
Extract this package zip file to a folder with a simple path
-
Copy or move the psf/cab files next to the script, then run one of the scripts:
psfx2cab_CLI.cmd
use cabarc.exe to create the full cab file / no progress info shown
psfx2cab_GUI.cmd
use DXTool.exe to create the full cab file / show GUI progress info
psfx2esd_CLI.cmd
use imagex.exe to create the full esd file / show percentage progress info
- Or from command prompt, run the desired script and provide path to the folder containing psf/cab files
example:
psfx2cab_CLI.cmd E:\Downloads\uup-converter\UUPs
- The result file will be located in the same folder (current or provided)
and it will have the same name of the original cab file, appended with -full_psfx
example:
windows10.0-kb5004564-arm64-full_psfx.cab
-
The script do not require administrator privileges
however, if you get Access Denied errors, run it as administrator -
CAB file has limitation by design: 2 GB size - 65535 included files/directories
if you are repacking big baseless update, it's recomended to create esd file instead
- psfx2esd_CLI.cmd is set to create the full esd file with max-compression ratio
if you want to create the file with solid high-compression ratio (require high amount of CPU/RAM),
edit the script and uncomment this line:
set compress=LZMS
