How to put Completed Files in a separate folder from Ongoing Torrent Files

[Lemonde]

I download a lot of torrent files and they are large files, so I usually put them in my external Harddrive to free up space in my computer. But it is hard to distinguish what is completed or in progress. I would like to know how to put a completed file in a separate folder when it finished downloading. I tried using Settings > Transfers Tab > Adding > Clicking Keep incomplete files in: and put in an Incomplete folder, it was ineffective. If there is something I am doing wrong or any good recommendation will be appreciated. I use a Mac so it is more restrictive.

To be clear, you do NOT want to use the incomplete folder? (Which sort of does what you want.) Then you may need to use a script instead.
