Project files and bundle Files
SONAR project files contain various project settings, any MIDI data, and references which "point" to
audio clip data. The audio data (and video data) itself is not saved in a project file. To save audio as
well, save your project as a Bundle file (extension .cwb). Bundle files contain everything that a
project file contains in addition to the digital audio. Bundle files are useful for backing up projects and
for burning onto removable media, like a blank CD or DVD.
The following are descriptions of both file types:
See “64-bit CWB files” on page 258.
To create a bundle file
1. Choose File > Save As to display the Save As dialog box.
2. Choose Bundle from the Save as Type list.
3. Enter a file name and click OK.
SONAR compacts all the audio and merges it with the remaining project data in a bundle file.
To unpack a bundle file
1. Choose File > Open to display the Open dialog box.
2. Choose a file with a .cwb extension.
3. Click Open.
If you have the Use Per-project Audio Folders option enabled in Edit > Preferences > File -
Audio Data, the Unpack Bundle dialog box appears. If this option is not enabled, the bundle file
opens and all audio data is stored in the Global Audio Folder.
4. If you want to store the project in its own folder do the following in the Unpack Bundle dialog:
• Enter a project filename in the Project Name field.
•Use the Browse button to the right of the Location field to select a destination folder for the
File Type Description When to Use
.cwp Contains MIDI data, project settings, and
pointers to audio data in your Data directory.
Project files contain no audio data, so they are
small. Backing up a Project file does not back
up the associated audio data.
Project files are good for routine projects. You
can use Project files and back them up as
Bundle files at various steps during a projects
development.
.cwb Contains all project data, including all audio
data. Bundle files are large.
Bundle files are useful for backing up projects
or for transporting a project to another
computer (to bring it to a friend's house, for
example).
