Been having this problem for a while. firevault and time machine are both turned off. I ran "OmniaDiskSweeper" and found a folder that contains all the deletes files. It's a folder called "hlink.ref" inside a folder called ".cleverfiles" I tried removing all the files from the folder but it basically put's it back on the same folder once they are deleted from trash bin. EDIT: I finally got most of the files removed somehow but how do I prevent this from happening again? Thank You.
