Torben,
That's a good idea, the original bulk upload did not unzip into directories, but I updated file-storage to work that way.
I am just not sure where that code exists (5.2 or HEAD)
We should be able to export from the old instance, (and make sure the export uses directories, I think it does) and then upload back into OpenACS. Maybe its possible to export the file and scp it over to the other server, and import frm the filesystem to save download and upload effort.
