Is there a .net/windows api way to get/set the fields of the summary
information in the file properties window? I know that this information is
stored as an alternate data stream in ntfs, but I cannot find a good way of
accessing it. If there is not a good way of getting it via api, is there a
good way to read/write fields in this stream?

Matt,

Here is a page that shows how to get it calling some API functions and
COM interfaces:

http://users.telenet.be/ws36637/properties.html

You could access this through the P/Invoke layer and COM interop to get
the summary.

I could have sworn there was an object that MS provided which made this
easier. If I come across it, I'll post the url.
