Sorry, something went wrong. Yes, always one file left. I assume it's the file that BleachBit was complaining about. It's usually empty as are all but the main file BleachBit uses to fill the file system with zeros , but all the random files have the same naming structure as the main wipe file, starting with "tmp" followed by a bunch of random characters.

It's been a while since I've wiped any hard drives, but I'll try doing some wipes when I have time so I can more carefully observe the behaviour.

You mentioned "it says it can't close. I remember seeing an error along the lines of "bleachbit can't close this file because a process is using it" or maybe it was "bleachbit can't close this file because a process is using it" now that I think about it, the latter makes more sense. I wasn't sure, so I edited that part out.

When I tested with a removable disk, Bleachbit successfully wiped it without issue. Though I think It was still creating those files at the end of the wiping process, but was just able to delete them all. I think this because I once saw it creating those files when I opened the drive I was wiping in WIndows explorer toward the end of the wipe.

After closing the program, only one file remains, like I previously said. Only difference is that the file that remains is empty while these files have a length of one. I regrettably didn't open the files in a hex editor to see what they contained, but my guess they might just contain a single null character.

I put in a change that might help. Would you please test BleachBit version 2. You could test it normally like you did, or for extra information try the command below from a console with administrative privileges. If you want more instructions on how to run this command, let me know. Fixed in What features does BleachBit have to securely wipe files? Today BleachBit offers these features Overwrite specific files found by its cleaners to hide the contents of these files such as Firefox Internet cache.

Overwrite specific files found anywhere on the hard drive such as a confidential spreadsheet on your desktop. Wipe free disk space to hide the contents of files previously deleted by any software. Wipe memory and swap to wipe data stored in RAM such as passwords and web pages currently, only on Linux. Are these features secure? Even more important than asking how secure an application or technique is, start by asking yourself What am I trying to hide?

Is worth a lot of money? A few thousand that is in your bank account? A one million dollar trade secret? How much harm could it do if disclosed? Embarrass someone? Hurt a relationship? Bankrupt a large company? Shift global political power?

Who would try to find it? A family member? A powerful rival company? A superpower government? How much time, money, and skill does that entity have? How much is it willing to spend to find your secrets? The answers to these questions will lead you to the appropriate level of caution.

Are multiple passes better than one pass? Limits of shredding files and wiping free disk space Shredding individual files and free disk space has limited benefits for any cleaner application, including BleachBit. The ideal case has three characteristics: The file size has never shrunk because of editing. Imagine starting with a 3MB spreadsheet, editing it down to 1MB using the spreadsheet application , and asking the cleaner application to delete the 1MB version: the cleaner has no way of knowing where the missing 2MB was allocated on the physical hard drive.

The file never moved. Imagine the spreadsheet software saves the document by writing a new copy to a temporary file, deleting the old copy, and renaming the temporary file to the original name. In this case, the cleaner application has no way of knowing where any of the old spreadsheet was located. The file system overwrites files to the same place. This is a good assumption. However, wiping free disk space has several of its own challenges: It can be slow, so many people are not willing to use it.

File systems allocate space in fixed chunks called a block size, and many files do not use all the last block.
