Is There More Functionality in the File System Way?

If you use a hashtag in most systems allow you to set an intent, then the allows for additional functionality not every system has that but but some do. And finally, obviously text, most of the time, I mean, especially in trickle but also in other systems. So tagging kind of comes out of this thing that information is easily duplicated or cross referenced within a digital system. It's interesting to think about things that are just incredibly difficult to do digitally.
