## What is it?

The iMovie Library in your Movies folder holds your iMovie projects and events, the clips you imported (copied into it), and render files iMovie creates for smooth playback. It often grows to tens of GB.

## What happens if you delete it?

Deleting the library deletes your projects and imported clips. Only the render files are recreated, automatically, when you play or edit again.

## How to remove it properly

To reclaim space safely, choose iMovie › Settings and click Delete next to Render Files. Delete events and clips you no longer need from within iMovie, or move the whole library to an external drive while iMovie is closed and open it from there.

## Before you delete it

Export finished projects (File › Share › File) before removing a library: once it is gone, the edit cannot be rebuilt.
