Drive Wiper leaves disk full, file cannot be deleted

CCleaner for Windows CCleaner Windows Bug Reporting
1

I've been using CCleaner for years, but this is the first time that I've used the Drive Wiper feature which I was quite happy to find. I chose to use free space only with 7 passes on a non-boot drive of 1.72 TB and let it run around 24 hours. It made it through about 60%, but today I needed to use the drive a bit. So I canceled the operation which was quick and easy.

But this did not free the space. I still have a file named "3590F75ABA9E485486C100C1A9D4FF06EGXJJQLXWOLTXWJK" at the root of my drive taking up 1.66 TB of space. I cannot delete it even in administrator mode due to the following error:

"File Access Denied

You need permission to perform this action

You require permission from the computer's administrator to make changes to this file"

This is on Windows 7 Enterprise 64-bit with CCleaner v4.10.4570 (64-bit). I searched around the forums but I haven't seen anyone else report this problem and get any useful feedback.

Trying to remove it in Cygwin says that it is removed but then doing an ls -la after that shows that it is still there (as does Windows Explorer).

Run the drive wiper again (but just use 1 pass) and let it complete.

Thank you, that still was going to take many hours to complete. Rebooting the machine was able to change or free the permissions on the file so that I was able to remove it.

Run the drive wiper again (but just use 1 pass) and let it complete.

Glad you got it sorted :)
