Finding things in Finder · Moved and offloaded apps in Finder
Will an app I moved still show up in my Applications folder?
Short answer: Yes. A shortcut stays in the same Applications folder, so the app still appears (with a small arrow) and launches from Launchpad, Spotlight and the Dock. It lives on the external drive and won't open while that's unplugged.
Yes. When Storage Studio moves an app, it leaves a shortcut in the same Applications folder, so the app still appears there — with the small shortcut arrow on its icon — and still launches normally from Launchpad, Spotlight and the Dock.
The app itself now lives on your external drive. While the drive is unplugged it can't open; reconnect the drive and it works again.
If you move it back from the Apps window's Moved tab, Storage Studio copies it into its original folder, removes the shortcut, and makes sure Spotlight, the Dock and Launchpad find it straight away.
