mkdir

I've got a web server which has files uploaded to it. There is a script which assigns them numeric IDs and stores them in a corresponding subdirectory.

I've now got 32000 of these uploads and that's too many for the server to handle in one directory. The script I'm using does have a way to "namespace" uploads so that ID 12345 - instead of sitting in /files/12345 - would sit in /files/namespaced/000/012/345.

The code can deal with this just fine, but I now have 32000 subdirectories in the wrong naming style. What's the easiest way to go through my existing files and put them in the right place?
