Many torrent clients have the option to move completed files from one folder to another, but this does not help if the Downloads folder already have things in them. I also prefer to sort my downloads according to my own hierarchy not the names and folders that they were named in the torrent.
Therefore I am more concerend in moving the file to a completed folder when I have stopped downloading and seeding.
The following script which depends on having Aversa
There are a few folder hierarchy variables that need to be setup but then it could be used to move files which no longer have a torrent file referencing them into another folder.
