You guys are talking about a Win32 thing called "structured storage".
The good news is that this stuff is documented in MSDN:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/stg/stg
/the_summary_information_property_set.asp
The bad news is that it isn't really easy.

Subject: RE: Setting extended File Properties
Well, I can't give you the answer, but I think I can point you in the
right direction.
I had an idea that perhaps this information is stored as an alternate
Data Stream. I capitalized that because it's a special concept in NTFS.
Anyway, I ran a script called "streams.pl" (from David Roth's book,
"Win32 Perl Scripting") on a test file where I had modified the "Title"
property and sure enough, I found a stream called "?SummaryInformation".
Note the special character in the beginning. I have no idea how to
access this stream. I tried running another script from Roth's book
called "streamdump.pl" using that exact name, but I got an error.
Anyway, my advice would be to do some searching on Microsoft's TechNet
on the subject of "streams" and "SummaryInformation". Or maybe
something like +"file streams" +"SummaryInformation" on Google.
Good luck, and post back if you find anything.
P.S. No - I didn't find anything useful in Win32, Win32API::File,
Win32::AdminMisc, nor Win32::NetAdmin.
