hi here is the shortcut for deleting a file peramanently without pressing shift+del.
To permanently Delete files without moving them to the Recycle Bin, hold down the Shift key while pressing Delete. To stop using recycle bin altogether, right-click the Recycle Bin and click on Properties. On the Global Tab, select Do not move files to the Recycle Bin. If you enable Configure drives independently, you can set this up for the drives you want to.
