# How can I see how much space Google Drive, Dropbox or OneDrive take up on my Mac?

Open **Preferences → Rules → Free Up Space includes** in Storage Studio. Under **Optimise cloud storage locally**, every cloud folder found on your Mac is listed with how much space its downloaded files take, plus a total of how much of your internal disk is caching cloud files. Use the refresh button to measure again.

Don't rely on Finder's **Get Info** for this: it reports the full size of every file in the folder, including online-only ones that take almost no space, so the number can be far larger than what's really on your disk.

Storage Studio's **Storage Profile** also lists big downloaded cloud files among your biggest space users, each with a **Free up** button. See [what Free up does](https://storagestudio.us/faq/freeing-space/what-does-the-storage-profile-free-up-button-do).
