   I *have* compared it Johnathan, and it's a whole big pile faster 
   than running a loop, which, of course, is the backup routine in 
   case the drive in question is HPFS (since warp intentionally 
   traps if you try this on HPFS with a wildcard spec).

   Think about it...which is faster, looping 500 times to do a 
   findnext/handle delete, or once to nuke the entire directory 
   contents?

   If BillieSoft had come up with some magical way to duplicate the 
   speed without using FCBs, they would have removed this from their 
   CLI a long time ago...
