mpeg files stuck on desktop

[David Noel]

Hi all --

-- I downloaded some mpeg files onto my desktop, and they have resisted 
all efforts to move them into a folder, with the message "the file ,,,, 
is being used by another task right now (other tasks include moving, 
copying. or emptying the Trash). Try again when the other task is 
complete."

-- This happens even if this action is the first thing attempted after 
restarting. Attempts to Duplicate one of these files gives "this 
operation cannot be completed because you do not have sufficient 
privileges for ....".   I can rename one of these files or move it 
elsewhere on the desktop, and that is all.

-- Looking at Ownership & Permissions under Info shows the file is 
unlocked and the Owner shown correctly, but 'Access' is greyed out. Any 
suggestions, anyone? TIA.
