I used Laplink Self-erase for the first time 3 weeks ago after my computer inexplicably started acting as if the hard drive is too full so it would freeze up randomly and have to be hard rebooted. I have Windows Vista, but I noticed Windows 10 users were having the same kind of mystery and they had no answers. I thought it might be some 0 day exploit so I got off the computer until now, and found I only had 54 MB left of free space on the hard drive. I'm redoing Laplink's Self-Erase now, and have reclaimed 700 MB with another handful of GB's ready to free up. But this program left behind a couple folders; C:\ OOSERUBBERC (from 3 weeks ago and it's about 200 GB with 1 bin file about that large and a quarter million 1 KB shortcuts OOSERUBBER2.BIN up to OOSERUBBER245093.BIN); and C:\ OOSERUBBERC1 (which is unavailable & empty as I write this while the program runs). My system hard drive is only 465 GB and was about half full before I started with the Self-Erase, which is a program that is supposed to overwrite previously deleted files with 0's and 1's. The program says to ignore the warning message that the hard drive is out of space while it does its thing, and the space should come back when it's done, but the computer might have froze up during that process. Should I delete this 200 GB folder of .bin files from the computer? The internet apparently knows far too little about this program to tell me much of anything in English, even with Google Translate.
