If only it were a unix system, you could:

  1) remove the file
  2) replace it with a file you can read
  3) replace it with a symlink to /dev/null

Is there a VMS tool for showing a list of all open files?

If you fill up your quota with a big empty file, does the keystroke
logging program crash and burn?

If so, can you still use the system afterwards?

Maybe try uploading files; the file transfer looks like keystrokes; a
63-block file transfer should do it.  Let the file be random garbage.

Also, doesn't VMS have the principle "If a file affects your quota, you
have control over it"?

Oh, and just in case it is a unix system, check for a filename
starting with a ".".  'ls -la | more' comes to mind.
