In Praise of OmniDiskSweeper
I’ve tried a bunch of these tools over the years, both graphical and text-based, but I still keep coming back to an oldie-but-goodie—and it’s free: Omni’s OmniDiskSweeper has everything I want in a disk space usage tool. It’s got an intuitive interface, and a way to either delete what I find or open the containing folder to take a closer look.
Perhaps it’s because I’m a column-view Finder kind of person, but I love the columnar drill-down layout that OmniDiskSweeper uses.
I keep coming back to it, too, because I like the interface. The biggest flaw is that there’s no built-in way to count files that the current user doesn’t have access to. However, you can use Terminal to run it under sudo.
