It ist the by ccleaner generated file for the wiping process for the free space on a volume. ccleaner shows the wrong unit in the status bar during the wipe proccess; after the MFT wiping. I will do it a second time and post later today to this topic a screenshot for a better description.
Hi, the CCleaner in the current version shows the file size of the erasing file for a GB volume and a GB size in MB, I mean: CC cleaner means, the file is 2,5MB, but the file is 2,5GB.
