WaveCache File
The WaveCache.wfm file stores all of the wave-
form display data for the session. If you delete
the WaveCache.wfm file, Pro Tools creates a
new one the next time you open the session.
By storing waveform data in the WaveCache
file, sessions open more quickly. The session
WaveCache file can be included whenever a ses-
sion is transferred to another Pro Tools system
(7.x and higher).
Pro Tools also maintains a distinct WaveCache
file inside the local Digidesign Databases folder
(C:\\Digidesign Databases), which retains
waveform data for all files used on the system.
Additional WaveCache files are created on each
hard drive attached to your system, and stored
in the Digidesign Databases folder on each
drive.
Deleting or trashing a WaveCache file does not
harm the session or your system. However, each
session takes longer to open because it has to re-
calculate waveform data for any associated au-
dio files and store that data in a new WaveCache
file.
Session File Backups Folder
The Session File Backups folder contains auto-
matically-generated backups of your Pro Tools
sessions. These files are created when working
on a session and the Operations preference for
Enable Session File Auto Backup
is enabled. (See
“Enable Session File Auto Backup” on page 85.)
Renamed Audio Files Folder
This folder includes file names that have been
renamed when you open a session that contains
audio file names with incompatible characters,
or, in certain situations, save a copy of a session
to a Pro Tools version that does not support
long file names.
Opening a Session
When you open a session, Pro Tools looks in the
session folder for audio and fade files linked to
the session.
To open an existing session:
1 Choose File > Open Session.
2 Locate the session you want to open and click
Open .
Opening a Session that Contains
Unavailable Files
DigiBase notifies you if files are located but re-
side on Transfer volumes (such as CD or DVD
discs), or if any required files cannot be found.
For more information, see “Locating Audio
Files” on page 309.
For more information, see “Renamed Audio
Files and the Renamed Audio Files Folder” on
page 311.
For more information on opening sessions
created on different platforms, Pro Tools
systems, or versions of Pro Tools software,
see Chapter 16, “File and Session Manage-
ment and Compatibility.”
You can also open a session from a Digi-
Base browser by double-clicking it.
