Project Structure

In Zrythm, work is saved inside projects. Projects consist of a directory with a project file describing the project along with additional files and directories used by the project, such as audio files and plugin states.

Backups

Backups are also kept in the project directory, and each backup is a standalone project on its own - ie, it contains all the files it needs to load as a separate project.

Projects inside the backups dir of a parent project are considered backups of the parent project.

Підказка

Zrythm will keep backups automatically by default during autosave. You can change the autosave interval or turn it off in the preferences.

Project File Format

Zrythm project files (project.zpj) are zstd-compressed JSON files (the project file MIME type x-zrythm-project is an alias of application/zstd).

Project files can be converted to JSON using:

zstd -d project.zpj -o project.json

Audio Pool

The audio pool (pool directory) contains all audio files currently used by the project. Zrythm will automatically delete unused files during save.

Примітка

These files will be copied to backups as well.

Project Compatibility

Project format is not expected to change in a breaking way. When we make changes to the project format, Zrythm will auto-convert old projects to the new format.
