Google Drive on the web lets you sort all of your files to see which files use the most storage space.
- Go to drive.google.com.
- Click More in the left navigation.
- Click All items.
- Go to the Sort menu and select "Quota used."
You'll see how much storage a file uses under Quota Used. If multiple versions of a file are in your Google Drive, you'll see the sum total of all versions of a file. Find out how storage is counted in Google Drive on the web.
