This may be a bit difficult to explain, but I'll do my best. So earlier today I was deleting a bunch of pictures in my Samsung galaxy tab a's gallery to get some storage back, and I accidently deleted the Autodesk preview folder. This may be unrelated to my problem, but since it happened right before it is a possibility. My actual issue though is that I cant open the gallery in the app with all my drawings. Whenever I try to do so the app crashes and forces me to exit. I'm am concerned because all my drawings are on this app and I'm not sure how I can access them now. Any help or knowledge in the matter would be greatly appreciated, thanks.
