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.
Recommendation for anyone trying to create space on their mac's. Got rid of over 50gb's of waste storage with this tool. Very helpful when your hdd is only 126 :)
