Sorry I wasn't clear on that point, my mistake.
What I meant is clear them from the media without clearing them from Gallery. And it was just a question in order to identify if it is feasible or not.

On another point, i have a case where they are deleted from the Gallery and still showing in the Media.
and of course when trying to open , the following message pops up:
" Can't open the file because it is damaged"

Therefore the need to delete

And no need to be sarcastic

Thanks
