Able to create folders

The possibility of creating folders would allow the best organization of the files.

Second this. We want to use folder upload functionality of IPFS in order to reduce number of transactions needed to "proof" items inside the folder (so one proof for all, rather then for each file individually); While still retaining the capacity to access the files from behind a single url (which is submitted with the proof).
