Perhaps the sentence could be reworded completely to reflect the intent.
I'm assuming it would be something like:
"How much NTFS bookkeeping data is required (which the system puts inside
the MFT zone) if you have 750000 small files?"
Or if we ask the same thing a bit differently: "How many files can you
have in an NTFS partition before a 1MB MTF zone gets full?"

Oh. MFT records are 1K, I think.
The "MFT zone" is different. That's an area of the disk that's right after
the main block of MFT that Windows tries not to put files into. It's there
because you can't defrag the MFT, so as the MFT grows, it's best to have
space right after it to grow into. However, if you *do* fill up the disk (or
use a defragger that moves files into there, d'oh!) you can use that space.
It'll just get allocated last of all.
If you look at the MyDefrag, one of the defrag options is to move files out
of that space.
By default, it starts at 12.5% of the disk, and you can half that or double
that when you format the drive, depending on your anticipated needs.

From defrag -v -a:
Master File Table (MFT) fragmentation
Total MFT size = 264 MB
MFT record count = 256,999
Percent MFT in use = 95
Total MFT fragments = 3

I would hate that 750K partition unless is fully defragged with
PerfectDisk 10 and even so the MFT would be big and searching a file a pain.

Exactly, thanks for the correction, I end up getting to the same
conclusion but is very reassuring when a English Language native give
you the right answer too :-) Spanish is mine, hence the confusion, when
you think "too fast" in a foreign language you end up mixing it with
your own and writing/saying phrases/sentences that won't make sense on
either language.

Exactly, the whole this is just MFT.
> It's there because you can't defrag the MFT,
Actually PerfectDisk 10 can among other optimizations it does at
Boot-time defrag, and even it changes its size to best fit a partition
when needed. Unless you have an NTFS encrypted filePerfectDisk 10
defrags *everything*, this give me the following brag right: don't blame
me for having the best defragger out there, hehehehe :-D

Clearly, it's *possible* to do so. :-) I'll keep that product in mind if I
ever need it.

oh yeah, if look into my first post I give a hint how to reduce the MFT
at the minimum size but, halve it when on the minimum setting that is
something I don't know how only PerfectDisk 10 does it; if you didn't
meant this I apologize for the misunderstanding.

I forgot to add that, IIRC NTFS was first introduced in HP Unix OS long
ago and it was called HPFS, then improved and used in WinNT 4.X NTFS
v.4), some more improvement in Win2K (NTFS v.5), little improvement in
WinXP (NTFS v.5.1 if I'm not mistaken, don't recall it clearly).
Improvement of course in speed, security, self-protection and fault
tolerant, even some viruses have problem damaging purposely the NTFS,
and you need to really mess around your PC a lot to have a warning in
the System Event Viewer (eventvwr.msc, System)and then an error message
saying the NTFS is damaged. Most of the times, not always, Windows will
start the chkdsk utility at boot-time to check and repair the File
System if the partition is marked as "dirty" (a byte on each partition
system area volume status area).
Cheers.
