I don't see any significant advantages over the other storage methods
we already have defined for Files and Blobs, specifically localStorage
and IndexDB. And there are significant advantages of using a database
to store files. For example if you're storing emails in a database,
you can just stick the attachments as a property of the emails. And
things like filename collisions and finename charset encodings and
case sensitivity become a thing of the past.

Note that just because the APIs expose the files as being stored in
the database, doesn't mean that the implementation has to physically
store the files in the database if that is bad performance wise.

And there security aspects involved as well. I'm not entirely
comfortable with any site being able to write just any file to my file
system. For example writing viruses or malware seems like asking for

The only use case I have heard for FileSystem over IndexDB is that
with FileSystem OS software like iTunes and iPhoto can pick up and
index music and images stored by the site. While neat, this doesn't
seem particularly urgent.
