# Uninstalling an app versus dragging it to the Trash

Dragging an app to the Trash removes the app but usually leaves its support files behind. Storage Studio's Uninstall finds those leftovers, shows them, and removes them recoverably.

On a Mac, the usual way to remove an app is to drag it to the Trash. That removes the app itself. Storage Studio's **Uninstall** goes one step further and offers to remove the files the app left around your Mac, too.

## What dragging to the Trash does

Dragging an app from Applications to the Trash removes the app. Its supporting files — settings, caches, saved window positions, sandbox data and so on — stay in your Library folder, because macOS can't be sure you won't reinstall the app later. Some apps come with their own uninstaller for this reason.

## What Storage Studio's Uninstall adds

**Uninstall** is in the Apps window, for apps on your Mac (**Internal**) and apps you've moved (**Moved**). Before anything happens, it shows a list:

- the app itself, which is always included;
- each leftover it found, with its size — such as **Cached data**, **Saved preferences**, **Sandbox container**, **Saved window state**, **Log files**, **Website data**, **Cookies** and **Background launch item**.

Untick any leftover you want to keep. Only items that clearly belong to that app are offered. If the app is open, it's quit first. Everything is then removed recoverably — to the [Recycle Vault](https://storagestudio.us/wiki/recycle-vault), or to the Trash — so you can change your mind. Apps installed by an installer may need your administrator password. For a moved app, the shortcut left in Applications is removed too.

## Using both

For an app you might reinstall soon, dragging it to the Trash is fine — its settings will be waiting. For an app you're done with, Uninstall gets the space back from its leftovers as well. If you might want it again one day, consider [offloading](https://storagestudio.us/wiki/offloading-an-app) it instead.

- **How do I move apps to an external drive on a Mac and still launch them?** Dragging an app to another drive can break it, because macOS expects it in /Applications. Storage Studio relocates the app to your external drive and leaves a shortcut in place, so it still launches normally from Launchpad, Spotlight, and the Dock — and you can move it back in one click.

- **How do I use an external SSD as extra storage on a MacBook?** Plug in a USB-C or Thunderbolt SSD and let Storage Studio pair it with your internal drive as one workspace. It moves big folders, libraries, and apps to the SSD with a shortcut left behind, so your MacBook behaves like it has a much bigger disk — fast enough to work directly off the external drive.

- **Can I move my Photos or Final Cut library to an external drive?** Yes — large Photos, Final Cut, and iMovie libraries are common space hogs. Storage Studio relocates them to an external drive while keeping them usable, leaving a shortcut so your apps still find them. Moving a folder to your fast drive keeps its files' modified and created dates, permissions,… (https://storagestudio.us/faq)
- **Will moving files to another drive break my apps or Spotlight?** Not the way Storage Studio does it. It leaves a shortcut (symlink) at the original location, so apps, Finder, and Spotlight resolve everything as if it never moved — and the move is fully reversible. (https://storagestudio.us/faq)
