I am already self-hosting Matrix for my friend group. I suppose where just gonna move more and more stuff onto there. Doesn’t fix the issue, but you don’t have to go quietly.

At some point, your SSD will fail. If you’re lucky, that is quite a while away. If you’re unlucky, that’s tomorrow. If your data is truly critical, at least copy it to a second drive, even if you don’t do a proper/full 3-2-1 backup.

Also, if you’re asking whether you can move data from one drive from an old file system to a new file system that replaces the old one on the same drive without copying data to a different drive - no.

If I’m not mistaken, illustrator is vector based, krita is pixel based. So drawing-wise, krita is closer to Photoshop than illustrator.
