Sorting by size is a useful start, but file type and location matter. A large video you created, an old installer, and an active virtual-machine disk may all need different treatment.
Use Finder first
In Finder, search a known location and use size criteria to narrow results. Review the file name, parent folder, and modified date before moving anything.
Look for categories, not just files
Large groups of files are often more revealing than one file: Xcode build artifacts, local models, browser data, or application support can explain a growing total. DiskClue indexes the largest files it can inspect and provides category context alongside them.
A careful next step
Use this guide to understand the storage you see, then make changes only after reviewing their purpose. DiskClue can help make the evidence easier to inspect in the current MVP.
