Drop an item into a Control (Filtering)

What is the difference between the two lines below:

Me.AcceptFileDrop FT_Images.All
Me.AcceptFileDrop ""

IMHO: none. It compile and run and I am able to get my images and other objects :frowning:
Even folder drop goes thru the Canvas (but I filter it with added code to the DropObject).

BTW: I know this is an old evil.

Your comments ?
(Preferably after testing the code above on Mac OS, please.)
