I download a lot of mp3's from Youtube using the Media Downloader extension with Firefox. I set up a workflow/folder action in Automator to watch my iTunes music folder and add any new mp3's to my iTunes library. The problem I'm running into is that the workflow starts looking for new files as soon as the download from Firefox starts. So, the result is that new songs don't get added to my iTunes library unless I run the workflow manually once downloads have completed. Is there any way to get the workflow to start AFTER the complete file has been downloaded?
