Workspace : Linking and Relinking Files : Choosing When to Relink
 
Choosing When to Relink
Pro Tools lets you relink files while opening a project or after a project is already open, as follows:
Relinking when opening a project ensures that the project opens with all media playable. Automatic and manual relinking can be performed. See “Opening a Project with Missing Files” on page 159.
Relinking later (after a project is already open) is the fastest way to open the project, but all missing items remain offline and unplayable. See “Relink Window” on page 119.
