Database files can be shared among users. This is particularly useful for Transfer volumes, eliminating duplicate processing (indexing) time.For example, shared volumes (such as network storage volumes) tend to be large, and indexing can be a time consuming task. To avoid duplicate effort, one user can manually index part or all of the shared volume just once, then email the database files to other users. Database files can be added by placing them within each user’s Volumes folder. Periodic manual indexing then keeps all databases current.Catalogs can be created for a particular project and then shared among multiple systems to help facilitate more efficient workflow. Catalogs are stored as database files on your system drive.On Mac, Catalog database files are stored in the Library/Application Support/Avid/Pro Tools/Databases/Unicode/Catalogs folder.On Windows, Catalog database files are stored in the Program Files\Avid\Pro Tools\Databases\Unicode\Catalogs folder.
