Session Files and Folders
When you create a new session, Pro Tools auto-
matically creates a new folder named for your ses-
sion. Within this folder is the session file, a Wave-
Cache.wfm file, and several subfolders (including,
but not limited to, an Audio Files folder and a Clip
Group folder).
Session File
The session file is the document that Pro Tools cre-
ates when you start a new project. Pro Tools can
open only one session file at a time. The session
file is appended with the extension .ptx.
Audio Files Folder
The Audio Files folder contains all audio recorded
or converted during the session.
When you record a new audio track, the track is
saved as a new audio file to the Audio Files folder.
You can also import other audio files into the ses-
sion, and work with them as well.
Fade Files Folder
The Fade Files folder may be present in legacy
Pro Tools sessions. Versions of Pro Tools lower
than 10.0 use rendered fades and cross-fades that
are written to the “Fade Files” folder in the session
folder.
Rendered Files Folder
The Rendered Files folder contains any temporary
files created by Rendered Elastic Audio
processing in the session. It may also contain tem-
porary filtered analysis files (.aan) as a result of
any changes to Elastic Audio analysis.
Clip Groups Folder
The Clip Groups folder is the default directory for
any clip groups that you export from your
Pro Tools session.
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 Wave-
Cache file can be included whenever a session is
transferred to another Pro Tools system (7.x and
higher).

different hard drive locations, including
shared media volumes, see “Recording with
