Mac Forum / Applications / Media Player / January 2006

I recently bought a used mac from a friend.  He said that he doesn't know
why but the desktop file WindowsMedia.sitx can not be moved, opened, or
deleted.  I would just like to delete it.  I have already take Windows Media
Player 9 off of the computer.

The message I recieve upon attempting to drag the file into the trash is :
 
     The item "WindowsMedia.sitx"  is being used by another task right now
(Other tasks include moving, copying, or emptying the Trash)

This is just not possible because I have tried to delete the file upon start
up it does not work either.

When I click on the file Stuffit comes up and says :

    An error has occurred while expanding the file "WindowsMedia.sitx"  
(Format error).   Error #17540

I do not know what else to do.
