I thank you for taking the trouble to reply to my question.
As I said I am 80 yrs old and I don’t think as fast as I used to.
When I plugged the device back in,A box came up with Open
Folder to view files which I did.There were 4 Folders in there and 4 Icons.
Then like a light had been turned on,I realised I had opened a FOLDER!!!!.
I then did as Veladem said and copied and pasted a film to that folder
and it worked.
When you get to my age,thinking and seeing what is staring you in the face
is not as easy as it used to be.
Again,thank you both so much for helping me,I really appreciate it.
You are both helpful and kind.
