Delete files from the Windows Recycle Bin does not remove it permanently from the hard disk. Nowadays, there are ways to recover them using special software. A file is removed definitively only when it is overwritten. Active @ KillDisk will make sure if a file is deleted permanently from your hard disk. It is a free program that is compatible with all Windows operating systems (both 32-bit and 64-bit) that allows you to securely delete data from local hard drives, USB drives and other removable storage media.
