Tree protocol info
The tree protocol uses the first 6 hex characters to identify the host, and the final 2 to represent the files, making it the shortest URI scheme I have found. To use the protocol, you will need to install a tree protocol tool. It will use your default browser (Tor works as well) to show the content, and can even be used to natively open files via file path.
Note that this doesn't happen automatically in your browser though, you'll have to use the tree protocol in your file manager.
