Many thanks, as usual, for your unstinted help.
I have followed your tip, and i found the images you attached very helpful.
However, i got stuck when I came to (Quote your wording) "Click on Edit and change the permission to deny for the users." (Unquote).

I do not understand how to make this step. Am attaching the image I obtained when I hit EDIt, but what is the next step?

My aim is to deactivate the shortcut option permanently from my pc, as I can never find the files that are invariably lost when any shortcut is deleted.

Sorry, cannot send attachment:- Modern technology tribulations !!!

Best regards and goodnight.

Joe
