The Norton one, which you "used to be able to get as a separate 
utility", fracking Norton..., would rearrange things so that a) commonly 
used files where all in the same space, things in the same directories 
where in the same space, actual directory data was located near the 
start of the disk, so it was accessed faster, and compacted "all" empty 
space, so that your existing files where at the start of the drive, not 
scattered all over the damn place. Then they came out with Win95, and 
some files got "locked" so you couldn't move them at all, never mind how 
fracking fragmented they got/made things, but it "still" used smart 
rearranging on everything else. Now.. I have no idea what it actually 
does, or it even technically available, especially as something other 
than part of 3-4 other things you don't need, and slow the system, do to 
them running in the background all the time.

I personally find it incomprehensible that nothing else anyone makes 
seems to be able to do anything as "simple" as compressing used space to 
the start of the drive, so your "unused" space is contiguous, never mind 
being "smart enough" to defrag that big 1G file, even without "enough 
room", by arranging other fragments to give you the space, instead of 
just leaving them empty. Its like handing a moron a paint brush and 
coming back to find themselves sitting on the top of the kitchen counter 
whining, "I painted myself into a corner!", only.. there are sections of 
floor, all in between them and the door, none big enough to jump to or 
step on, but never the less "unpainted", which they planned to "get back 
to later". :p And, that the MS defrag takes the idiot amount of time it 
does to paint itself into that same corner... Obviously mentally 
challenged, "as well as" stupid. lol
