|File Eraser (Windows) - All versions
Previous versions of files and folders are generated automatically by Windows Backup on certain operations and may leave your data recoverable if not processed properly. These previous versions can be used to recover lost data in case it was accidentally modified or deleted. This feature is a potential security risk as sensitive files can be recreated – even if they have been deleted.
Windows Vista and Windows 7 both automatically save copies of your documents in case you accidentally erase one and need to quickly retrieve it. Blancco File Eraser can target and erase both the original copy as well as the backup.file/folder and the "previous versions" of it.
By default, when user is starting an erasure for selected file or folder they will prompted with an extra dialog (shown in the below screenshot) asking whether the user wants to include the previous versions into the erasure. Note that this operation requires elevated privileges in order to target all the necessary files/folders.
