I am sort of doing that now. I use a program called ‘Remove Old Files’ to delete the empty folders (ie.tmp) in the library every 1 minute. There could be a timing issue if you automated coping the files. I ran into that and cutoff half a show.
The best solution, if development was still being done, would be for Tablo Ripper to allow you to select the location of the tmp folder like they do the Output folder or just change it to use the program data folder or the TabloRipper folder.
