# What large files are usually safe to delete on a Mac?

Common safe candidates, after a quick check that you don't need them:

- **Installers and disk images** (.dmg, .pkg) in Downloads once the app is installed.
- **Archives** (.zip) you've already unpacked.
- **Old Install macOS apps** you don't plan to reuse.
- **Old iPhone and iPad backups** for devices you no longer have.
- **Screen recordings and exported videos** you've uploaded elsewhere.
- **App caches** for apps that rebuild them.

Avoid deleting anything in System, Library folders you don't recognise, and app-support data unless you know what it is. If you're unsure whether you'll need something, move it to an external drive instead of deleting it. See [moving folders](https://storagestudio.us/faq/moving-folders/).
