I checked the file's properties and the read-only option was already off.  I tried turning it on and off again, but I still have the same problem when trying to delete files. Once I have tried to delete a file, I get a  ' Dir File error! It might be in use '  the window's  " File Edit Commands Tools Help"  menu at the top becomes unacessable, and at the bottom it says it is deleting 1:1 files, however it stays like that indefinately without changing. 
 Suggestions?
