I used the move function to one of my photo folder at mycloud.com. For some reason the folder disappeared after the move. (move from one folder to another folder in the same parent folder)
Then I tried to use testdisk from other posts, I can see all other deleted file in testdisk except the photo folder i’m trying to recover.
Have you tried logging in via SSH and examining the mycloud’s file system? Once you have logged in, just cd /shares and navigate from there. Use ls to see what’s there, or Google if you need a linux command primer.
