Actually, looking it up on MSDN, it seems more complicated than I
thought. :-) But not something I feel like persuing.

Um, not according to wikipedia:
http://en.wikipedia.org/wiki/Comparison_of_file_systems
Sparse files are supported on NTFS but not any variation of FAT. Then
again, that table doesn't show NWFS or NSS as supporting sparse files
(which they both do), but lists them as "unknown".

Note that there is an ellipsis there. Most likely the full name was
"ntuser.dat.LOG".

The .LOG is a constant 32KB. Still doesn't match the 1KB he saw.

At this particular point in time, that file is exactly 1 kB for this user
account on my machine. The size can vary over time, but 1 kB seems to be a
minimum.

Good call. Yes. ntuser.dat.LOG is 1K, 4K on disk, and shows as having 32
fragments today. Considering 1K of data would (AFAIK) fit in the file
table itself, it shouldn't even have *one* fragment. I suspect there's
something funky, like a whole bunch of contiguous "fragments" listed or
some such.

Again, the time factor. But at least on that topic I *can* claim some
expertise.
