## Link to iTunes if Modified

All selected files which are not currently linked and which have been modified, will be linked to iTunes. This is useful when running an action in the Batch Processor and you want to avoid linking unless necessary.

If the Ignore errors option is selected, errors will not be reported. You can use the Linked to iTunes Test function to determine if an error occurred.

The default linking method is based on searching iTunes for metadata contained in the tracks. This is the preferred method of linking. If you have previously linked a track to iTunes and have retained the iTunes PID, you can elect to link via the retained information. This functionality is primarily intended for users starting to work on tracks contained in iTunes which have little or no metadata. You can drag the tracks from iTunes to Yate, linking them, and save the PID for later use. Note that a retained PID has no meaning in any iTunes library other than the one from which it was obtained. Further, upgrading iTunes to a new version or rebuilding your iTunes database may invalidate any retained PIDs. The PID must be retained in a UDTI named iTunes PID.

The following sequence can be used to retain a PID after linking normally:

> Get Property iTunes PID -> Variable 1
> Import value of a User Defined Text Item with name 'iTunes PID' from Variable 1 (create)

The following sequence can be used to remove a retained iTunes PID

> Remove User Defined Text Item with name 'iTunes PID'

Depending on your Preferences - iTunes settings, it is possible that certain iTunes metadata is also imported to the tracks after successfully linking.
