If you see sub folder it doesn't comes from ubb.threads. Attachments are stored in one folder only and Gizmo already describes how to find it. But if this directory the place for gallery pictures you see subfolders by number. This number is the ID of the gallery forum inside ubb.threads.
The folder ubb.threads/uploads is clean on my site. I setup a attachment folder outside the ubb.thread basedir long time ago. Maybe newer installations use this folder as default attachment folder. In the attachment folder files will be stored by number only with newer versions of ubb.threads. Old versions (< 7.6.x ?) store it by number, followed by filename.
