# Full Disk Access

Full Disk Access is a macOS privacy permission that lets an app read files in protected places. Storage Studio asks for it so it can see and move what uses your space.

**Full Disk Access** is a macOS privacy permission. It lets an app reach files in places macOS otherwise protects — such as other apps' data folders and parts of your Library. You give or remove it in **System Settings → Privacy & Security → Full Disk Access**.

Storage Studio asks for it so it can see where your space is really going, including in protected places, and move files there without breaking them. Without it, many large folders would simply be invisible to it.

When Storage Studio asks, it opens the right page of System Settings for you. Turn on Storage Studio in the list and it notices on its own — there's no need to relaunch.
