Help with Dell PFS extractor

[openminded]

GUIDE TO USE DELL PFS EXTRACTOR or other extractors from BiosUtilities (my way)

1. Download BIOSUtilities (thanks to platomav) and move folder "BiosUtilities" to Desktop
https://github.com/platomav/BIOSUtilities
2. Install python 3.11.0 or higher (both versions for 32bit and 64bit)
3. Download Dell bios update from Dell site (in my example bios update for Dell Latitude 3420) and move it to "BiosUtilities" from Desktop.
4. RENAME update exe WHITOUT SPACES AND DOTS! In my example "Latitude_3420_Latitude_3520_1.37.0.exe" to "Latitude_3420_Latitude_3520_1_37_0.exe"
5. Open cmd as admin and go to folder "BiosUtilities" from Desktop. For win10 win11 drag&drop "Dell_PFS_Extract.py" [space] "Latitude_3420_Latitude_3520_1_37_0.exe" and hit Enter. (for win7 use copy/paste)
6. For ALIENWARE use "Insyde_IFD_Extract.py", is not AMI bios but Insyde!

Thank you for the write up. I pretty much did that and Python never got added to PATH.
When trying to run from the dir, all kinds of dependencies didn't work, because Python couldn´t even finf standard libs.
Absolute Windows related garbage, since in the PATH variables, I did see the directories set properly - they just didn´t have any effect.
After losing many hours trying to solve that and getting sick and tired of it, I ran it once on Linux and it just works, despite the author writing about compile errors.
So for anyone having those PATH issues, or any other, I recommend using Linux.
