# How do I find the biggest folders on my Mac with Storage Studio?

Open What's Using Space and look at **Biggest on this disk**. Your largest folders are listed biggest first, and you can open any of them and keep going as deep as you like, so you land on the thing actually responsible instead of a top-level folder.

Folders appear as each one finishes being measured, so the list fills in rather than making you wait. Any row can be revealed in Finder, and **Collapse all** resets the view.

When you find something you want off your Mac, use the row's action or see [Move to fast drive](https://storagestudio.us/faq/freeing-space/what-is-the-move-to-fast-drive-button).
