Performance and Transfer
Volumes
DigiBase lets you view, manage, and import ses-
sions and media from both Performance and
Transfer volumes.
Performance Volumes
Are storage volumes (hard
drives) that are suitable for playback and have
been designated in the Workspace browser as
Record and Playback (R) or Playback Only (P) of
media files in a Pro Tools session.
Transfer Volumes
Are volumes that are not sup-
ported for media playback in Pro Tools (such as
shared network volumes or CD-ROMs), or stor-
age volumes (hard drives) that have been desig-
nated in the Workspace browser as Transfer (T)
volumes. Transfer volumes
cannot be used to
record or play back media in a Pro Tools session.
Designated Transfer (T) volumes can be useful
for transferring session and media files between
different Pro Tools systems.
Digidesign Databases
The information displayed in browsers is stored
in individual databases. Pro Tools creates these
databases automatically for all mounted vol-
umes, including Transfer volumes.
Digidesign databases use three file types:
volume.ddb
Stores media and session file meta-
data for a particular volume.
catalog.ddb (DigiBase Pro Only)
Stores media and
session file metadata for a user defined Catalog.
Cataloged media and session files are can reside
on multiple volumes, including Transfer vol-
umes.
Wavecache.wfm
Stores waveform overviews for
all audio files referenced by each session.
Read/Write Volume Databases (Hard Drives)
For each volume, a database file is created in a
folder named Digidesign Databases, on the root
level of the volume. The database is stored with
the volume it describes so that if the volume is
later moved to a different system the database
does not have to be recreated.
For more information on volume designa-
tions, see “Audio and Video Volume Desig-
nators” on page 196.
If you delete the Digidesign Database
folder, all existing database information for
that volume is lost. To recreate a deleted
Digidesign Database folder, re-index the
volume (see “Indexing DigiBase Data-
bases” on page 172).
