Is your computer running Windows 7
operating system? As everyone knows, if files
get deleted by Shift + Delete keys on Windows 7, they will be removed
immediately from the location and you can no longer restore them from Recycle
Bin. Therefore, we often think that shift + delete keys is a way to erase files
permanently from a computer. If you want to undo Shift Delete and restore files
permanently by pressing Shift + Delete keys, you need to rely on professional
data recovery software.
