Minimizing Files
You can minimize the audio files according to the size of the audio clips referenced in the project. The files that are produced using this option only contain the audio file portions that are actually used in the project.
This can significantly reduce the size of the project if large portions of the audio files are unused. Therefore, the option is useful for archiving purposes after you have completed a project.
This operation permanently changes the selected audio files in the Pool. This cannot be undone. If you only want to create the minimized audio files as a copy, leaving the original project untouched, you can use the Back up Project option.
Minimizing files clears the entire edit history.
Procedure
Result
Only the audio portions that are actually used in the project remain in the corresponding audio files in the Pool Record folder.
