Usually projects on github. Personally I use Appimages for things like Mypaint a digital drawing application, krita and most other KDE applications as to avoid all the dependency's KDE has in its eco system or at least to put them somewhere easier to manage
Interesting read, love stuff like this but it seems they'd be a lot of dev overhead to truly make something large and agnostic but still gotta commend it!
You'll have ask the question of how important is this data, then before you start run drive diagnostic tool to see if all are functioning as expected, I'd suggest moving directories aposed to chopping anything up as to maintain some form of redundancy if a drive were to fail. It'll be a long process. Hope it goes well
Ill do it
