So I pretty much love the Windows 7 Libraries feature, and saw one use for them that I thought would be perfect, but I can't seem to manage it. Basically, a merged view of different folder structures.

Suppose I make a new generic library and add three locations to it: C:\Test\, D:\Test\ and D:\temp\Test\. Now, these may look somewhat okay as long as there are no duplicates in these folders. (It wants to group them based on the included directory, which one can work around by looking on google - I don't have the precise trick on hand I am afraid.)

But when you get collisions and, say, two of those directories have a Sub directory in them, stuff becomes unusable (assuming Arrange by: Folder view). You'll have multiple folders listed named Sub, which is pretty useless when looking for data.

I want folders to get 'merged', which ought to be possible somehow since it can create these merged views based on artist, album etc in other views. So all subdirectories that are double (and recursively checking for doubles inside those, etc) ought to be merged for as far the View is concerned. If files have a collision, I don't really care what happens - hide one, show both, filter out duplicates, whatever. (Although an option would be nice...)

Anyhow, is there anyone who knows how to get such a 'merged folder structure' functionality for Libraries? It would be really useful for me.
