Q: after I deleted some files on my computer, although most important things are covered repeatedly, with file recovery software like FinalData, Recuva to scan, we still could see partial file names. Please tell me how to operate to delete these files completely?
A: some pulverizers are useless, such as 360 and Rising’s, just could delete the files failing to be deleted with common measure, still there’s recovery possibility after deletion. So you’d have to use professional pulverizer, here I recommend you these tools: Data Shredder, Eraser, Wipe, Zilla Data Nuker, File Shredder and so on. If you don’t want to use third party software, you could use Windows accompanied tool “cipher.exe” in Windows 2000 above version. The usage is simple, in command line window, enter “cipher /w:(drive volume):\(directory)” and execute. (Without the brackets, just fill the actual volume and directory you use) After the command starts running, take turns to use 0X00, 0XFF and random number to cover all spare space of the partition, finally to erase the trace of any deleted file. Pay attention: this command is only for the disk of NTFS format.
