How to delete duplicate projects and videos You don’t want to screw up one or all of your projects accidentally. But I’d caution you not to move, rename or delete anything in this file unless you know what you’re doing. There you’ll be able to see each project and all of its assets. If you want to go into the library file, you can do that by right-clicking or holding down the Option key and clicking on iMovie Library. You can find the library file in your Movies folder in Finder or by clicking Go > Home > Movies. It creates a library file that stores all your projects and the corresponding assets for each of them. IMovie acts in the same way that Photos does. But in no way should it be used to replace frequently saving your project on your own. With that much strain on the app, it could cause iMovie to become unstable and crash more frequently.Īll that to say, autosave is a great backup. Plus, the more video files you add to a project, the heavier the file will be, and the more resources that project will require to run. And then, ultimately losing all of that work you did in the interim. But you should still get into the habit of periodically hitting command+S to save your projects.īecause the autosave is based on time, it’s possible you could do a ton of work on a video and have iMovie crash in between autosaves. So, any videos, images, or audio you drop into your project will be saved.

Yes, as you’re working in iMovie, it will periodically save all of your movie assets into a library file. Keep reading to see how iMovie handles your files and what you can do to optimize the storage on your hard drive. This is why it’s a good idea to stay organized and manage your files, so you’re not wasting storage space. But video files are large and can take up a lot of space.

It’s an app that will scan your Mac for duplicate files and then lets you quickly delete them just by clicking the Smart Cleanup button.
