It pauses automatic actions, asks developer apps that commonly hold files on the drive to quit, then ejects. If something still has files open, the eject fails safely and tells you. Before you unplug your external drive — to take your laptop somewhere, or to use the drive elsewhere — eject it from Storage Studio. It pauses Storage Studio's own work, asks apps that commonly keep files open on the drive to close, and then ejects the drive the way macOS does. ## How to eject 1. Choose **Eject Drive…** from the **More** menu. (In the Advanced view's menu-bar popover, it's **Eject NVMe** under **More**.) 2. Storage Studio asks **Eject your external drive?** and reminds you that relocated folders and apps won't be reachable until you plug the drive back in. 3. Click **Eject**. 4. When it's done, a notification says the drive was ejected and is safe to disconnect. ## What happens when you click Eject ```mermaid %% caption: What Storage Studio does when you eject the drive flowchart TD A[Click Eject] --> B[Automatic actions are paused] B --> C[Developer apps that often hold files on the drive are asked to quit] C --> D[Wait for them to close, up to 15 seconds] D --> E{Does the drive eject?} E -->|Yes| F[Notification - safe to disconnect] E -->|No| G[Notification - files still in use] ``` *Flowchart — What Storage Studio does when you eject the drive. Outline:* - Click Eject - leads to Automatic actions are paused - Automatic actions are paused - leads to Developer apps that often hold files on the drive are asked to quit - Developer apps that often hold files on the drive are asked to quit - leads to Wait for them to close, up to 15 seconds - Wait for them to close, up to 15 seconds - leads to Does the drive eject? - Does the drive eject? - Yes: leads to Notification - safe to disconnect - No: leads to Notification - files still in use - **Automatic actions are paused**, so Storage Studio doesn't start moving or cleaning anything while the drive is going away. - **Apps are asked to quit politely.** Storage Studio asks a short list of developer tools that often keep files on the drive open to quit — Xcode, Simulator, Android Studio, Docker, OrbStack and JetBrains IDEs — in the same way as choosing Quit from the app's menu. An app with unsaved changes may ask you first. - **It waits up to 15 seconds** for those apps to close, then ejects. ## If the eject fails If any app still has files open on the drive, macOS won't let the drive go. Storage Studio shows a notification saying **Eject failed** with **Files still in use**, and nothing is harmed — the drive stays connected and working, though automatic actions stay paused until you resume them. Quit the apps you were using with files on the drive (including any moved apps), then try again. The **Activity Log** in the **More** menu records which apps were holding the drive. See [Eject fails: "Files still in use"](https://storagestudio.us/wiki/eject-fails-files-in-use). ## After you plug it back in - Relocated folders and moved apps work again as soon as the drive is back — see [When your drive is disconnected](https://storagestudio.us/wiki/when-your-drive-is-disconnected). - **Automatic actions stay paused** until you resume them. The Home screen shows **Automatic actions are paused** with a **Resume** button once the drive is back. ## Good to know - **Ejecting from Finder** works too, but Storage Studio won't pause first or ask apps to close. - **Don't unplug in the middle of a move.** A move onto the drive waits and continues when the same drive is back; a move back from the drive stops and can be started again — see [The drive was unplugged during a move](https://storagestudio.us/wiki/drive-unplugged-during-a-move). - **Remount Drive** in the **More** menu tries to mount the drive again if it's plugged in but not showing up.

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.
