Try analysing the drive with MyDefrag (http://www.mydefrag.com). It will
show you what file occupies any given part of the disk.

The size of the MFT will of course depend on the amount of files on the
drive, but can easily be 100 MB or more.
Also, keep in mind that Windows will by default reserve up to an eighth of
the drive for the MFT to grow into. Not all defraggers distinguish between
the two parts.

Cool. He needs some SEO in there. I never found that, even when I was
looking for better defraggers. :-)

I think the allocated space is 1KB for each file, for the maximum number of
files you've ever allocated. I.e., 1KB per file, but it never shrinks.

Actually, it's at least 1/8th, and you can bumpt it up as high as 50% when
you first format the drive if you want. In case you know you'll have lots of
tiny files.

Here's some immovable files:
System restore files
Control panel->system->system restore
turn it off for now
USN journals
fsutil usn queryjournal c:
write down max size, allocation delta.
fsutil usn deletejournal /d c:
Frees the space. Takes a minute or so, actually.
Sync/checkdisk/reboot/whatever
Defrag (and pagedfrg if you're on xp)
Then turn back on system restore and
fsutil usn createjournal m=maxvalue a=alocdelta c:
See if that gets rid of your bits. Plus disk cleanup, of course.
Also, perhaps you at one time recycled a whooole lot of files, such that
your subdirectory under the recycle bin is especially large?
cd c:\$RECYCLE.BIN
dir /a

Speaking of which, on a slightly different topic...
When I boot and auto-login, it takes about 3 minutes before everything is
all settled down and happy.
If I log out, then log back in again, I'm back within maybe 5 seconds,
because everything's already in RAM and such.
I bet the thing would boot way faster if it just loaded the entire
executable for everything it needs to load at the time the program is
launched, rather than letting demand paging fight it out. I have enough RAM
to comfortably hold everything I run, so why not? I guess that'll get put
in eventually. :-)

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

Simplest answer is, it behaved that way in 3.11, when it was "even more
critical", and MS never bothered to steal the idea of fixing it from the
few companies whose products **did** do it. ;)

Huh? Did MS make a defragmenter for Win3.11? I thought it was just the dos
defrag? All the third-party defrags I remember using did a fine job of
defragmenting absolutely everything.

Cite? Certainly the XP defragmenter moves files around to open up free
spaces. I suspect it's just files that have absolute addresses in them,
like the UNC and system restore points.
Hey Warp, if you get it defragged, let us know what it was? :-)

Everyone uses the same API. If there's a reason the files can't be moved, no
program is going to be able to move them.

Clearly it isn't that simple.

Ah ok, I checked on my XP box and there is a -f flag, to force defrag even
with low freespace - maybe this would help Warp?

Why can't you just copy all the files while the OS isn't running? eg from
another PC/OS/LiveCD/boot disc?
