Start with Storage settings for a short list of large files. Use Finder for a specific size threshold, or a disk map when you need to understand whole folders. The best method depends on the question you are trying to answer.
Open System Settings → General → Storage, then open Documents if it appears. Review Large Files or Downloads and sort by size. Select a file and use Show in Finder to understand where it belongs before removing it.
Apple also provides a File Browser in the Documents category on supported macOS versions. These built-in views are a useful starting point when you want a list of candidates without installing an app. Apple describes the available Storage controls.
02 Find files above a size threshold
Open Finder and press Command-F. Select This Mac or the folder you want to search.
Open a search-attribute menu, usually labeled Kind, and choose Other. Find and select File Size.
Set File Size → is greater than → 1 → GB. Adjust the threshold to suit your disk.
Review the results in list view. Preview a file with the space bar and inspect its location before moving it to the Trash.
Search results depend on indexing, permissions, and the location you selected. A missing result does not prove a folder is empty. A collection of small files can also occupy substantial space without any individual file meeting your threshold.
03 Use Terminal for a folder overview
These read-only commands inspect your home folder. The first finds individual files larger than one GiB. The second reports allocated usage one directory level down, including hidden directories.
find "$HOME" -type f -size +1G
du -h -d 1 "$HOME" | sort -h
Permission errors mean some locations were not measured. Do not hide those errors if you need to know whether a scan is complete. You can inspect the command behavior on your Mac with man find and man du.
04 Look for the folder behind the file
A Photos library, a virtual machine, or a build directory can be the real source of growth. Deleting a few large files will not solve an accumulating cache or a project that keeps producing new exports.
Review your Downloads folder for installers and exports you recognize.
Manage Photos libraries, virtual machines, and device backups through their owning apps. Do not remove unfamiliar files from inside a library package.
Delve displays file and folder sizes as a treemap or sunburst. Follow a large region into its contents, inspect the path, and use Quick Look to identify a file before making a decision.
A visual overview complements Finder: it makes a large collection of small files easier to notice. Scan the folder relevant to your problem and check any reported access limitations. For a broader choice of tools, see our Mac disk analyzer comparison.
06 Finish with a deliberate cleanup
Move only files you understand to the Trash. Check that your project, library, or app still has what it needs, then empty the Trash when you are ready to make removal permanent. Recheck available storage on the same volume.
Yes. Use a Finder search with the File Size attribute. Results depend on the search location, indexing, and permissions.
Can I find large folders without an app?
Yes. Storage settings includes folder browsing on supported macOS versions, and the du command can show usage by directory. A disk map provides another way to explore the hierarchy.
Will deleting a 10 GB folder free 10 GB?
Not necessarily. Files still in the Trash, APFS shared blocks, and snapshots can make the recovered space differ from the folder total.
