In that case, I might have some code for you. Ill fish it out.

Subject: Re: [DUG] determining file system
Thanks Matt - at this stage I would be happy to be able to just identify
that the file is being served up by a netware server or similar. If we can
identify that situation then we can just ignore the datetime value which
will do for now.
Cheers,
Phil.

Hi Phil.
I spent ages some years back trying to sort out something very similar.
I can't entirely remember the details, but Fat, Fat32 and NTFS store
datetime information differently from each other.(Others may know the
exact details). Primarily I believe the difference between these windows
formats is whether or not the locale / regional settings are applied.
From memory NTFS stores according to GMT while FAT systems store
according to regional settings. For example, try looking at a files
creation date and time, and then turn on daylight savings settings and
watch the date and time change, so frustrating if you are trying to
synchronise files as we were. Windows automatically alters the date/time
and all of a sudden your date time is out.
There is a call to tell you the operating system of a volume, but there
are some difficulties, for exmaple:
Machine 1 (FAT) accessing file on Machine 1 (FAT)
Machine 1 (FAT) accessing file on Machine 2 (NTFS)
Machine 2 (NTFS) accessing file on Machine 2 (NTFS)
could all produce different values.
If you want I can dig out some code for you that is supposed to strip off
the locale information on those FAT volumes but the problem is when you
access from Machine 1 to Machine 2, you don't know what locale
information is being applied on the second machine. So you can never
really cover all bases.
Depending on what you are attempting to do if you have control of all the
files that go in there in the first place, you may want to consider
embedding datetime information into the filename or some index database
alongside it.
Other people might have some better solutions.
Matt.

Hmmm, not quite what I need. I'll keep looking. Cheers,

Part of our code depends on getting the file stamp of a particular
file, however on systems that have that particular file served by
something like Novell Netware, that timestamp can be something other
than what was expected.
Is there a way to determine the file/operating/network system (whatever
is the correct one to check) of a given location?
Cheers,
Phil.
