Anyone know if there are methods to alter the properties of files such as "Date Created" or "Date Modified" or even extended attributes such as an image file's "Star Rating" or tags, comments or even the Image ID?

I attached some example images of what I am talking about.

Check out the FileInfo class. This gives access to creation, access and modified dates. Not sure about tags and the like, possibly the FileInfo.GetAttributes method might return these (and SetAttributes to modify them?)
