You see every item and its size first, untick anything to keep, and everything removed can be put back. **Uninstall** removes an app and the leftover files it has spread around your user Library, such as caches, preferences and support files. Before anything happens you see the full list with sizes, and you can untick any leftover you want to keep. Nothing is deleted outright: everything goes somewhere you can get it back from. ## Uninstalling an app 1. In the [Apps window](https://storagestudio.us/wiki/the-apps-window), click **Uninstall** on the app's row, on the **Internal** or **Moved** tab. On the **All Apps** grid, right-click the app and choose **Uninstall…**. 2. Storage Studio looks for the app's leftovers and opens a sheet titled **Uninstall** with the app's name. 3. Read the list. The application itself is always included. Every leftover is ticked; untick any you want to keep. If nothing else was found, the sheet says **No leftover data found — just the app itself.** 4. Check **About … will be freed** at the bottom, then click **Move to Trash**. If the app is open, it's quit first, so it can't hold files open or recreate them while they're being removed. You'll see **Quitting …** and then **Moving … and its data to the Trash…**. ```mermaid %% caption: What happens when you uninstall an app flowchart TD A[You click Move to Trash] --> B[The app is quit if it's open] B --> C{Does every item pass the safety check?} C -->|No| S[Nothing is removed and the sheet says why] C -->|Yes| D[Items go to the Recycle Vault or the Trash] D --> E{Anything left that needs an administrator?} E -->|Yes| F[macOS asks for your password or Touch ID once] E -->|No| G[Done.

The app leaves the list ## What it looks for Storage Studio checks the places macOS apps keep their files in your user Library and lists each one it finds, with a plain label: - **Application support files**, **Cached data**, **Log files** - **Saved preferences** and **Per-device preferences** - **Sandbox container** and **Shared app group data** - **Saved window state**, **Website data**, **Cookies**, **Web cache**, **App scripts** - **Background launch item** For a moved app, the list also includes the copy on your external drive and the shortcut left in its place. ## Why it's safe - **A strict safety check.** An item is only listed, and only removed, if it sits in your user Library, an Applications folder, or Storage Studio's own folder on your external drive, *and* its name matches the app. A whole folder such as your Caches folder is never a candidate. The check runs again just before removal. If any item fails it, nothing at all is removed and the sheet says which item was stopped. - **Nothing is deleted outright.** Items go to the [Recycle Vault](https://storagestudio.us/wiki/recycle-vault), which keeps them on your external drive when it's connected, or to the Trash if the vault can't take them. You can restore them from there. - **You always see the result.** If something couldn't be removed, the sheet stays open and lists it, so an uninstall never half-finishes silently. ## Apps that need your password Some apps are installed by an installer as protected, system-owned apps. Removing those needs administrator rights, so macOS asks for your password or Touch ID. One approval covers every remaining item, and they go to your Trash. If you cancel that prompt, the sheet says "Couldn’t remove: …. This app needs administrator access — if you cancelled the password/Touch ID prompt, try again and approve it." If some items stayed because the app was still running, it suggests quitting the app and trying again. ## Offloaded apps An offloaded app is already off your Mac. To get rid of it, use **Remove** on the **Offloaded** tab. See [Offloading and restoring an app](https://storagestudio.us/wiki/offloading-an-app). ## Uninstall or drag to the Trash? Dragging an app to the Trash leaves its caches, preferences and support files behind. **Uninstall** finds those too and shows you exactly what will go. See [Uninstalling an app versus dragging it to the Trash](https://storagestudio.us/wiki/compared-with-dragging-an-app-to-the-trash).

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. (https://storagestudio.us/faq) - **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. (https://storagestudio.us/faq) - **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.
