# Which leftover files does Storage Studio's Uninstall remove?

It looks in the standard places macOS apps keep per-app files in your Library and lists what it finds for that app, for example:

- application support files and app scripts
- cached data and log files
- saved preferences and saved window state
- the app's sandbox container
- website data and cookies the app stored

It only includes items whose names clearly belong to that app, and you see every one, with its size, before anything moves to the Trash.
