What is the Purpose MFS

Im new to using IPFS and would like to know the point of MFS. Can someone please give a couple sentences explaining why and when it is used?

Thanks,
Eric

It gives you a mutable filesystem for managing files stored in IPFS. It allows you to name your IPFS files (while leaving them in ipfs), organize them into directories, etc. However, because they’re still in ipfs, you can still share them via an /ipfs/QmId path.

Basically, it’s a nice(er) user interface for IPFS (that still needs to be significantly improved).
