Currently we support just files. But there are APIs such as Directory API and the blink filesystem-subset API (also called Entries API) that support directories.
Michael, are you interested in this?
As we talked about on IRC, clearing for now.
Is this about bug 1289255?
I thought we had directory DnD?
This is about DnD for the Directory Upload API. It's still unclear if we want to have it.
There will be some discussion about the future of Entries API and Upload proposal on Friday. Currently it is very much unclear whether we want to expose Upload API or not.
I think this is a duplicate of bug 1289254.
This is either a dup of the dnd part of Entries API, which we already implemented and shipped, or this is about the Upload proposal, which we have no plans to ship atm. Perhaps INCOMPLETE is good enough.
