In Windows OS'es you can right-click properties on a file from the file
explorer and view various info (meta data) about the file on the Summary
tab. Meta Data includes things like Title, Subject, Author, Comments, etc.
How do I access (get/set) this info programmatically?

You need a custom wrapper around the OLE Structured
Storage-COM-Interfaces. The VB.NET MVP Eduardo A. Morcillo has already done
this. You can download his library here:

The library itself is written in VB.NET, but this doesn't matter of course,
as long as it is .NET. Eduardo provides a powerful example.

Have a look at this post as well:

and this post (in german, just look at the code)

Eduardo has build a custom wrapper around the COM-Interfaces IStorage,
IStream, etc. which are implemented in ole32.dll.
