How does cubase delete the cpr file of the guide rail? Urgent! ! ! ! ! My disk space is full and I want to delete it.

I'm not sure what you want to ask. If you don't plan to keep the cubase project, just delete the folder where the project is located.

If you plan to keep this project, you need to streamline the whole project in cubase. You can try the following means.

Unfreeze all tracks.

Automatically clean up useless audio in the media pool.

Minimize all audio in the media pool.

The edited audio will automatically replace the original audio in the media pool.

Empty the trash can in the media pool.

After saving and closing the project, select the folder where the project is located for automatic cleaning.
