How to SET extended file properties?
<p>I am talking about properties you see in file properties->summary (Author, Title, etc) I already know how to GET them by using shell32.dll class, and I asumed that I could also SET them with the same class, but it seems like writing extended properties is a little bit more difficult and shell32.dll doesn't allow to do that. I was unable to find a clear solution for SETTING properties (though there are a lot about getting them). 
Also found something about taglib-sharp, which seems to have an option to SET extended properties, but I don't really understand how it works. Maybe there are better solutions than that.
If it helps, I need to SET value only for Company field for some Word, .pdf documents.</p>
