  I have noticed a similar problem. So here's MY theory.

Everytime 4DOS deletes a file, it goes through the whole routine to get the
path and print it out. Even with the /q option, it may still be going through
the same mess. I set up the alias  "deldir command /c del %1" when I want to
do some "serious" kills.  (CP/M lives!)
