DaisyDisk is a paid disk space analyzer for macOS. It displays a sunburst diagram of files on a hard drive to help with the location or deletion of large files. It can display previews of files using Quick Look. It also allows the user to look at the file directly in Finder, in order to delete it or move it elsewhere.
With the new version DaisyDisk 4.21, you can connect and scan your cloud disk accounts, such as Dropbox™, Google Drive™ and Microsoft OneDrive™, in the same way you do with your local disks. Check what's taking space in your quota and remove unneeded files.
