reported vs actual file sizes

reported vs actual file sizes

[Paul Lai]

After installing cygwinb20.1 on a few machines, there's been some troubling
observations made.  Hopefully someone on this mailing list can answer the
questions.

There are 3 machines: NT 4.0 SP3, NT 4.0 SP4, and Win98.
The NT 4.0 SP4 and Win98 "Windows Explorer" provides file size information in
the "usual" way, and in a new way, which I'll called "used"; To get to the
file size info, select a file and use File|Properties.  

An example info box could contain something like:

        cut.exe
        Size:	24.0KB (24,576 bytes), 32,768 bytes used
                ^^^^^^^^^usual^^^^^^^  ^^^^^^used^^^^^^^

An "ls -l cut.exe" reports the "usual" size.

On NT SP4 with a FAT (32??) filesystem, all the cygwin-b20.1 binaries,
...\cygwin-b20\H-i586-cygwin\bin\*.exe, have "used" file sizes that are
multiples of 32,768 bytes.  This seems very unreasonable, especially in the
case of:

        true.exe
        Size:	395 bytes (395 bytes), 32,768 bytes used
                ^^^^^^^^^usual^^^^^^^  ^^^^^^used^^^^^^^

On Win98 with FAT32 filesystem, the "used" sizes seem to be multiples of
4096bytes.

The Windows binaries, explorer.exe, doesn't seem to have this problem.

So, the question is:
Is this a problem w/ my configuration of Window98/NT or is there
something wrong with the file/io stuff within cygwinb20.1?

I'm sorry I cannot answer your questionning, but I'd like to add more
to the fire
(forgive me).
I used 'du' to assess where I was wasting so much space on my disk and
surprise
surprise, I met a few problems :
1/ it does not list all directories and/or files (it has nothing to do
with
hidden directories or not)
2/ the count on individual directories and totals are way off what
windows
reports (file|properties)

It also shows things windows does not show :
3/ I listed the [c:\windows\temporary internet files] and though my
explorer
options clearly identify all files to be listed (including hidden
files) windows
explorer does not show some files that du counts and ls shows.

I'm on a windows95 system with FAT16 if this helps.

Regards,
Al.
