I can't see anything in Chishm's library to rename or move files or directories on a FAT file system. DSOrganize can rename files but its source code is not available for download. Am I missing something in the docs or header, or will this be implemented, or is it a WONTFIX?

Currently not implemented because of the way it removes directory entries. At the moment it only deletes the short file name, leaving an orphaned LFN, which isn't good, but won't cause long term disc damage.

If you want to move or rename a file currently, you'll need to open the destination, open the source, copy the source to the destination, close the source, then remove the source.

I should have this fixed next release. It's looking like I'll be doing a major rewrite, so don't expect anything soon.

dsoranize is pretty slow in renaming (there's a progress bar), so I have a feeling DragonMinded is simply copying then deleting original.

Duplicating the data seems very wasteful, seeing as a directory entry is just a pointer to the first cluster. Making a new entry for a zero byte file, then swapping the first cluster seems more reasonable.

Exactly :)
