I'm curious about this cause it happened to my file. It was an installer that I was moving from the desktop to another Local Disk. I let the operation complete while I was doing some other stuff in the background. So I pressed Ctrl Z for the hopes of undoing my permanently delete mistake, unfortunately its unrecoverable (the one I was doing in the background), but suddenly it undid the Move operation, now it goes back to the desktop. I cancelled the operation without it reaching 10%. The remnants are still present at the desktop. So I moved it again and confirmed the merge folder request. What I'm asking is that did the whole thing broke some files because I cancelled the move operation while at progress, but I moved it again, so I am thinking like I reattached a joint or something.
