Pro Tools Reference Guide172
Pro Tools also maintains a distinct WaveCache file
inside the Databases folder, which retains wave-
form data for all files used on the system.
Deleting or trashing a WaveCache file does not
harm the session or your system. However, the ses-
sion will take longer to open because it has to re-
calculate waveform data for any associated
audio files and store that data in a new WaveCache
file.
Session File Backups Folder
The Session File Backups folder contains automat-
ically-generated backups of your Pro Tools ses-
sions. 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 129.)
Renamed Audio Files Folder
This folder includes file names that have been re-
named when you open a session that contains au-
dio 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
Fade Files
When opening a session created in a version of
Pro Tools lower than 10.0, Pro Tools calculates
and plays back all fades in real time. The “Fade
Files” folder in the session folder is neither deleted
nor used. Any rendered fades created in legacy ses-
sions are calculated and played back in real time.
Any new fades created in the session do not gener-
ate any new rendered fade files in the pre-existing
“Fade Files” folder.
For more information, see “Renamed Audio
Files and the Renamed Audio Files Folder” on
page 397.
For more information on opening sessions
created on different platforms, Pro Tools sys-
tems, or versions of Pro Tools software, see
Chapter 18, “File and Session Management
and Compatibility.”
You can also open a session from a DigiBase
browser by double-clicking it.
Sound Designer II (SD II) files are not sup-
ported with versions of Pro Tools higher than
8.0.3. When opening a session created with a
lower version of Pro Tools that uses the SD II
file format, you are prompted to convert all
SD II files to WAV.
