DTPO 2 metadata - Information vs. Properties

In another thread, Bill pointed out the usefulness of the Groups window - thanks, Bill! I think that the Groups, Information, and Properties windows available via the Tools menu will be very useful!

My guess is that I can/should use the fields available in the Information and Properties windows to attach metadata to the files in my databases. What are the similarities and/or differences between those two collections of information? Also, it seems easy to edit the fields in the Information window, but how can the Properties fields be edited?

Any suggestions about how to best use those windows/tools would be greatly appreciated. Thanks!
