Put the name of the directory in quotes:

RMDIR "J:\RCS4\DATA\926FW\104-1999-20-19-33"

>I am trying to remove a directory -'RMDIR J:\RCS4\DATA\926FW\104-1999-20-19-33'and get an 'Access denied' message. If I try and remove the same directory with 'RMDIR J:\RCS4\DATA\926FW\104-1~UP'(DOS name)everything works fine.Is there anyway to remove the directory using the full directory name?
