Update:
Deep scan completed and returned 169 files worth 267GB. But as I recall, about 600 -700GB of that drive was used. I wonder what those 25,882 ignored files are tho.
By the way, quick scan with scan for non-deleted files showed 2 useless files only, so I'm gonna do a deep scan for non-deleted files.
And as I'm yet to buy a drive to recover those 169 files too, can I hibernate/sleep my pc till then?
