Not necessary. I'm running CCleaner always with those boxes unchecked.

Or - and that might be in my case - the user is to blame. I've been using CCleaner now for a while, but that problem never really occured, partially because I've never had larger files. But I've recently started converting my DVD-collection, and that produced quite a few larger ones. Occasionally some need to go (conversion issues), and now I've started losing hard drive space because CCleaner won't properly delete the larger files. So maybe, possibly, I'm the "bug" here. Who knows.

Apparently the files are in the recycle bin (hidden file) on the hard drive. Deleted them now without CCleaner, because CCleaner won't do it for whatever reasons. Odd.

Done. And nothing happens. Though the file is in the include list, it is not deleted. The file is marked for deletion when clicking analyzing, but CCleaner apparently does not delete it ("0 bytes deleted") that way. Deleting it the "regular" way (delete -> recycle bin -> then using CCleaner) produces the usual result: the file is deleted, but the space is not cleared.

I'm as confused as you are. I am using secure file deletion. I delete the file and then use CC, which, as previously mentioned, works fine with smaller files, even if their combined size exceeds, say, 3 GB. It just doesn't work with larger single files.

Nope. Cleanup doesn't show any files to clean, and if I run it, nothing changes.

Close, but not close enough. If I've understood the thread correctly, his/her problem is that CCleaner does not delete the file. It remains where it is, and shows in the analyzer. My problem is that CCleaner actually deletes the file (it's no longer on the drive and doesn't show in the analyzer), but it still hogs the same space. Example: I've recently deleted a movie (file size: 3 GB) with CCleaner. CCleaner deleted the file very quickly (which shouldn't happen), but the 3 GB of space that should now be freed from the hard drive are still "occupied". The analyzer does not show the movie to be there anymore, and this happens with all larger files. It's not that huge a problem, but eventually I'll have to format the hard drive in order to get that space back, which is something I'm trying to avoid.

Already have, the problem persists. Besides, the odds of two corrupted recycle bins at the same time that otherwise worked fine seemed low to me.

Yes, no problem.

No, that's not it. The recycle bin is emptied, no problem there. Besides, CCleaner's "inability" to delete large files happens on both my PCs (1 laptop, 1 desktop computer). Weird enough, it happens only with large, single files. If I delete, say, 5 files with 500 MB each, CCleaner has no problems. It's only large single files which cause problems.

It usually takes some time for CCleaner to clean files (depending on the settings). Yet when I try to delete larger files (>2 GB), CCleaner "deletes" it almost instantly. Unfortunately nothing is really deleted. The file seems to be gone, yet the space it occupied is still there (Example: I have 220 GB free hard drive space. I delete a 2 GB file. The file's gone, yet I still have only 220 GB of space, instead of 222). Is there something in the settings I've missed? I use Windows 7.
