Hi
it looks like i found a way to get ride from deleted files that you have physically deleted from your mac, but they have't been really deleted. (pardon me for my English)
1st, you got to have (OmniDiskSweeper), and (Clean my mac).
2nd, Open OmniDiskSweeper and choose your drive, which is probably ( Macintosh HD).
3rd, Choose .cleverfiles.>hlink.db. you will see so many files that you deleted in the past but they are still in your mac.
Now in the page of OmniDiskSweeper at the very bottom at the left corner, you'll see a white file picture, press it and a window will pop out, select all the files by clicking ( Command+A) now right click on the touchpad, from the menu choose (Erase Using Clean my mac).
Now Clean my mac will pop out and you'll see al the file you selected to delete. you'll see a circle at the bottom of Clean my mac that says ( Shred) press it.
now you will have gotten rid of some of the others lol.
