Find What’s Filling Your Disk with OmniDiskSweeper

It’s annoying when your Mac tells you you’re low on disk space and you can’t imagine what could be occupying it, other than maybe the 400 pictures you took at Austin’s beautiful Mt. Bonnell. Or maybe you know you’re running low—a good rule of thumb is to keep at least 10% of the drive free—but aren’t sure which files or folders are hogging the most space. Visualization tools like GrandPerspective and DaisyDisk can help you see what’s using your disk space, but if all you want is a simple hierarchical browser, the free OmniDiskSweeper is worth a try. It sorts your folders by size, and you can keep drilling down to find and trash the largest items you no longer need. The screenshot shows that the now-discontinued ChatGPT Atlas browser is still consuming several gigabytes of cache space—a good reminder to delete the entire app and its files!
