Here's every method for finding them, from built-in tools to visual disk analyzers. By [MbApps](https://lumadisk.com/about) · Published May 7, 2026 · updated October 1, 2026 · 5 min read **Short answer:** For a quick list, open System Settings → General → Storage and click the ⓘ next to Documents, then Large Files. To search the whole Mac, press Command-F in Finder and filter by File Size. Neither shows which folders are heavy, so for a full picture use a disk space analyzer that maps every folder and file by size. ## Why Finder Falls Short Finder can sort files by size within a single folder, but only within that folder. To find the largest files across your entire disk, you'd need to manually open dozens of directories. There's no global "sort all files by size" view. For most people, this makes finding large hidden files nearly impossible without help. ## Using Storage Settings On macOS Ventura and later, open System Settings → General → Storage and click the ⓘ button next to Documents. The Large Files tab lists your biggest documents, largest first, and you can delete from there. It is the quickest built-in answer, but it only covers your own documents, not apps, caches or the folders behind System Data. For those, see [what's taking up space on your Mac](https://lumadisk.com/guides/what-is-taking-up-space-mac). ## Using a Finder Search Finder's search can filter by size across the whole Mac, though the option is hidden: - Open Finder and press **Command-F**. - Under "Search:", choose **This Mac**. - Click the **Kind** pop-up, choose **Other…**, tick **File Size** and click OK. - Set it to **is greater than 1 GB** (or 500 MB for a longer list). Spotlight-based search like this skips system and hidden folders, and it lists files only. A 30 GB folder of 2 MB photos never shows up. It works well when you already know what kind of file you are after, like `.dmg` installers or `.vmdk` virtual machine disks. ## Using Terminal Experienced users can find large files with a Terminal command: find ~ -size +500M -not -path "*/.*" This finds all files larger than 500 MB in your home folder, excluding hidden directories. To rank folders instead, `du -sh ~/* 2>/dev/null | sort -h` prints the size of each top-level folder in your home directory, largest last. Both work, but reading the output takes some comfort with the terminal, a whole-disk run can take several minutes, and you have to repeat it one level deeper each time you find a heavy folder. ## Using a Disk Space Visualizer The most efficient method is a dedicated disk space analyzer. LumaDisk, free to download with a 7-day trial of everything, renders your entire disk as an interactive sunburst chart. Every file and folder is visible, sized proportionally to how much space it uses. Large files and bloated folders appear immediately as the biggest wedges. You can click any wedge to see what it contains, drill into folders with a breadcrumb trail to keep you oriented, and reveal a file in Finder, or queue it into LumaDisk's Bin and reclaim it without leaving the app. Reclaiming deletes permanently rather than moving files to the Trash, with ten seconds to undo before it commits. What would take 20 minutes of Terminal or Finder detective work takes under a minute with a visual tool. LumaDisk also flags the space hogs that are easiest to miss: build caches like `node_modules` and Xcode's DerivedData, plus duplicate copies of files you already have elsewhere, so you can reclaim gigabytes with confidence. Other good disk analyzers exist for the Mac, including free ones.

If you're unsure what a file is, look up its directory path before deleting. - **Can it be moved instead of deleted?** Large media files, project archives, and old backups are often better moved to an external drive than permanently deleted. - **Is there a newer version?** Old disk images, virtual machine snapshots, and exported files may be duplicates of files you still have elsewhere. LumaDisk shows you exactly what each file is and where it lives before you delete it, so you're never removing something blindly.

In Finder, press Command-F, set the search to This Mac, add the File Size attribute and set it to greater than 1 GB. For your documents, System Settings → General → Storage → Documents → Large Files gives a sorted list. To see folders as well as files across the whole disk, use a disk space analyzer. ### Why can't I sort Finder by size across all folders? Finder only sorts the folder you are looking at, and by default it does not calculate folder sizes at all. Turning on "Calculate all sizes" in View Options helps within one folder but is slow, and still never ranks the whole disk. ### Is it safe to delete large files I find? Files in your own folders, such as old videos, disk images and downloads, are yours to delete. Leave anything inside /System and /Library alone, and check what an app support folder belongs to before removing it. Moving big media to an external drive is often better than deleting it. ### What is the best free tool to find large files on a Mac? GrandPerspective and OmniDiskSweeper are free and show the whole disk, as a treemap and a sorted list respectively. WizTree now has a Mac edition that is free for personal use. LumaDisk keeps scanning and its sunburst free after a 7-day trial.
