Regarding what and where something is... Let's look at two examples of most-used aspect of folders. A document file and photograph file. For me, the least efficient aspect comes with not being able to store a single document at multiple places (folders). If I have a document on Subject A written by Author B and C (two authors), than I may want to have this single document show up at multiple places, for example, the Subject A for me could be XYZ, ABC etc. The best I can do is create shortcuts of this file in a multiple folders (I shouldn't duplicate the file). So here, the tags would come handy. Now, I don't know about you but I have spent significant amount of time thinking over how to folder my photographs (and I am not a professional so not talking in GIGs). All in all, the folders are not very efficient on their own.
