I ran testdisk in order to recover one partition out of two with some important files on it. Testdisk brought back the partition with three folders: "$RECYCLE.BIN", "saves" (this is what I was looking for) and "System Volume Information". Shortly, everything that partition had on it.
The problem: all folders appear as empty. The "saves" folder has 16,4kb which it can't be. Also, the partition's free space is 19,7GB out of 22GB. Obviously, the files are still there, taking space up, but not showing up.
P.S. I am seeing this using a live-usb. After using testdisk and rewriting the partition table I get "error: no such partition. Entering rescue mode..." I don't know about this either. Maybe because it is in front of the ubuntu partition.
