If JEmplode is going to use the new structure, then it MUST be clever about it, preferably in the same way as Hijack. Otherwise we are going to see infinite confusion and pain as a result.

For any fid retrieval, first look for the the subdir'd fid, and if that fails, then look for the flat directory (original style) fid.

For any fid WRITE, only *only* use a subdir if at least one subdir already exists. If at least one subdir already is there, but the one you need is NOT on either drive, then create it and then upload the fid to it.

And again, use /emped/fids[01]/* as the base pathname for everything.

Cheers
