I’m going to switch from Windows 11 to Linux soon but first I wish to backup every every data and config files I can in my current Windows installation, even those that wouldn’t natively work in Linux. I know the \Users folder is important to back up, but I don’t know what other directories I am missing.


I did this, and installed the old drive into a USB adapter so I could easily pull any documents I may want to access. The Linux install will mount a NTFS drive, so worked great for that.
For the OP, while you CAN have the PC boot up to the Windows drive plugged into USB, I would not recommend doing it more than a couple times. Windows seems to hate this; I’ve had two installations of Win10 Pro eat itself and become unbootable, could not be repaired. The files were still accessible through Linux though so was able to make copies.
