Synchronization is the primary function of SuperSync. It allows you to grab and play music files from different libraries, either locally (on your machine's hard drive) or remotely.
Files that reside on remote or secondary libraries are
available for synchronization. Files can be selected for
synchronization by left-clicking on the file name in the main library
viewer. Multiple files can be selected in a range by holding down Shift while clicking or by individually added to the selected group by
holding down Command (CTRL on Windows) when clicking. When a file in a
remote or secondary library is selected (indicated by the blue sphere),
synchronization is by choosing one the following options:
During the synchronization process, SuperSync copies the
selected file or files into the designated your music directory. The
status of this transfer is displayed in a new window that launches upon
the beginning of synchronization. This status can also be displayed by
pressing +T or selecting Transfer Status from the Controls menu.
To synchronize playlists, select a playlist and synchronize the tracks. When all tracks are "Green" and exist in both libraries, you can go to the "Action->Synchronize Playlists" menu (also available by right-clicking the playlist) and get or put the playlist. Playlists will then be added to iTunes.
If there is an error, you'll need to look in the Log Window to find out why a playlist did not transfer. Possible reasons include duplicate playlist already exists, playlist uploading disabled, older copy of SuperSync running (requires version 2.1 or greater.) etc.
One warning about playlists. It is strongly advisable not to have playlists with the same name. This is legal in iTunes, but it is not programmatically possible to always tell them apart using the developer tools available.
