# What happens if an app is using a file when Storage Studio wants to move it?

Storage Studio checks first. The move confirmation lists every app using a file inside the folder, with a **Quit** button for each, **Quit all**, and **Recheck**. Quitting is always graceful — it's never a forced kill, so the app can save its work.

macOS's own housekeeping services, like Spotlight indexing, are left off the list; they can't be quit and don't interfere.

For moving things back, an amber **Force move back** option lets you proceed anyway — files that exist only on your built-in drive are always kept. See [What's Using Space](https://storagestudio.us/manual/whats-using-space).
