True, although the current implementation mostly matches FileStorage. Scott, did you set up a blob directory? If so, the files you uploaded should have landed in the blob directory. When you removed the files and packed, they should have been removed from the blob directory. Please confirm that is happening as it should. If you did not set up a blob directory, then the files must have ended up in the database somehow. Oracle may require some kind of maintenance in order to reclaim that space.
