I don't believe that there is an event for this.

You might have to use a SQL Lite query against the tables to figure out if a file has been synced and then delete that file. Probably against the DEVICE or DEVICE_TRACKS tables.

Is there an event for after a file has been synced with a device? I'd like to write a script to delete or move podcast files after they have been sent to a device so they won't be re-synced again. Not seeing an event that will help trigger this.

Thanks
