Linking and Relinking Files
For more information, see the following topics:
A Pro Tools session is made up of references, or links, to audio files and other session media. Audio and video files must be stored on suitable Performance volumes and be properly linked in order to be playable in the session.
The following types of files are not playable:
Transfer Files
Files that are stored on volumes not suitable for playback, such as network volumes or CD-ROMs.
Missing Files
Files that cannot be found where the session expects them, either because they have been moved, or because they are stored on volumes that are not currently mounted (offline volumes).
The process of reacquiring missing files is referred to as relinking. Relinking can involve certain sub-tasks, depending on the situation.
*   
Transfer files must first be copied to a suitable Performance volume. The session is then relinked to the copies on the Performance volumes instead of the original Transfer files.
*   
Volumes may be searched for missing files and, when the files are found, Pro Tools relinks the session to the file's new location.
*   
Files that reside on offline volumes must first have their volumes mounted (brought online) before they can be relinked.
