Wipe free space ccleaner12/10/2023 ![]() ![]() (This is more or less how CC and Recuva work, based on posts in this forum. ![]() Those large files can be seen and I believe secure deleted with Recuva, but it would be pointless to do that. But if I choose Wipe Free Space Only then the file names are still visible (in Recuva). Wipe Free Space is separate from WMFT as CC writes large files of zeroes over every free cluster it can find until the disk is full, then it deletes those files. However, all Ive been able to find out is that if I do Tools - Drive Wiper - Wipe Entire Drive then the file names are completely removed (Recuva shows no results). Those previously overwritten entries will be overwritten again. You can rerun CC with Wipe MFT enabled as often as you like. (But they are, as Ident points out, of no use to man or beast anyway.) So secure deletion will not work on these files. You will need to learn and understand how it works to be effective. Eraser, on the other hand, erases files, folders and/or free disk space. In fact just use DBAN defauts for those times you want to start all over with a fresh drive, OS, applications, etc. Files under 1k are mostly held in the MFT entirely. DBAN is great for rebuilding systems from scratch. ![]() You can look at these deleted entries using Recuva. If you tick Wipe MFT Entries then CC will count the number of deleted entries in the MFT, and create that amount of files with around (I think) 800 bytes of randomish data so that all the deleted file names and info are overwritten. The MFT contains entries for live and deleted files. Also WFS is pointless and add's unnecessary strain to your hard drive. Firstly WFS does not send any files to a folder. It's not a great idea to do things you are not sure of. My question is: As Ccleaner wipes the files and puts them in a folder - if I ran 'wipe free space' again for safety using Ccleaner or Stellar Wipe, which I've just bought, would the files within Ccleaners folder, which it deletes after a wipe, be able to be wiped again or does it mean, because their in a folder, no further wiping can take place? My opererating system is a standard Windows XP for home use. I used Recuva and found the files but could not overwrite them as it was grey'ed out and could not restore as it was in the MFT and 'Access is denied'. I've just started using 'wipe free space' and noticed that Ccleaner wipes all files to a folder with a long number that it then deletes. I love Ccleaner and think it's a great program. ![]()
