## What is it?

Disk images (.dmg) are how most Mac apps are distributed outside the App Store. Once you have dragged the app to Applications, the .dmg in Downloads is no longer needed. This rule lists disk images older than 30 days.

## What happens if you delete it?

Not recreated, but you can download the installer again from the developer’s website if needed.

## How to remove it properly

Check that the app is installed (double-click the .dmg to see what it contains, then eject it), then move old .dmg files to the Trash. Sorting Downloads by Date Added or Size in Finder helps find them.

## Before you delete it

Keep a .dmg if it holds something hard to get again, such as an older app version you depend on, or an encrypted disk image with your own files.
