# Does Uninstall remove an app's system helpers or extensions?

Storage Studio's Uninstall covers the app and its per-app files in your Library. Some apps — security tools, VPNs, drivers — also install system-wide helpers or extensions in protected places, and those aren't part of the list.

For apps like that, use the developer's own uninstaller if it has one; it knows exactly what it installed. You can still use Storage Studio afterwards to sweep up any leftovers in your Library.
