# How do I completely uninstall an app and its leftover files on a Mac?

In Storage Studio, open the Apps window and click **Uninstall** on the app (from the **Internal** or **Moved** tab). A confirmation screen lists the app plus the leftover files it scattered across your Mac — preferences, caches, support files, saved state and similar — with sizes and the total you'll free. Confirm, and everything goes to the **Trash**, so you can put it back if you change your mind.

The app is quit first if it's open. See [what leftovers are removed](https://storagestudio.us/faq/apps/what-leftover-files-does-uninstall-remove).
