# Can Tuhi explain things like System Data, purgeable space and local snapshots?

Yes. Tuhi knows general Mac storage, not just Storage Studio, so you can ask what **System Data** is, why your disk looks full, what **purgeable** space means, what **local snapshots** are, or whether it's safe to clear caches.

It explains in plain English and, where Storage Studio can help, adds the button for the right screen — for example **Open Local Snapshots** to see how much space they hold. For more, see [Local Snapshots](https://storagestudio.us/manual/local-snapshots).
