I should have noted that merely renaming and "re-adding" from within the original book folder (created by calibre) results in a 0-byte file.
I suspect the official method would be to skip your first two steps,
1) go to the storage folder.
2) move the file somewhere else
and use the Save book option instead (to avoid messing with calibre's book storage and getting wierd errors). Then delete from the db and re-add it after renaming. Unfortunately, it's no faster.
