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.


Best option is a new seperate drive of course.
But besides that I can recommend making a image of the drive ans storing it somewhere. This way you can flash everything back, there would be a ton of applications that would not run if you try and restore the files only.
Last option should be to customly copy files from folders around. This would not guarantee you can restore Windows. But you maybe would be able to restore config at a much lower storage amount
