$this, of course, assumes that your disc is basically full, or with the
$files distributed evenly across the disk.  i also dont remember were
$exactly the fat table is on msdos and i dont know how often msdos
$read/writes it.  i suppose if the fat table is at the front of the
$disk and you dont have any disk caching, then yes, the front of the
$disc is where you want to put important stuff.

   Yup, all the administrative stuff (except for subdirectories) is
at the front of a DOS disk - the FAT and the root directory, primarily.
This is why it makes sense on DOS to have the most important files at the
front of the disk.
