iTunes Folder Watch 2.x | 1.4 MB

iTunes Folder Watch synchronizes your local files with the ones on your iTunes. It allows you to set up "Watch Folders" and to evaluate whether there are any new tracks in them which do not exist in iTunes, and allows you to add them selectively or fully automatically.

Are you frustrated that iTunes does not automatically detect new tracks in certain nominated folders and add them to the library automatically?

iTunes Folder Watch can be run as a taskbar process and so will continually monitor the watch folders. You can also run iTunes Folder Watch in the foreground if you want.
