Sorting storage by folder size is the fastest way to free up disk space, but native operating systems handle this task very differently. While some platforms allow you to view cumulative folder sizes natively, others require specialized third-party tools or search workarounds to hunt down storage-hogging directories. Windows (10 & 11)
By default, Windows File Explorer cannot native-sort folders by cumulative size in the standard directory view. It only displays individual file sizes. However, you can use these built-in or external methods to achieve it:
The Storage Settings View: Go to Settings > System > Storage. Click on Installed apps or Other to view a native, pre-sorted breakdown of your largest system categories and directories.
The Explorer Search Trick: Open your target drive in File Explorer, click the top-right search box, and type size:gigantic (or size:>1GB). This forces Windows to surface all individual heavy files across subfolders, which you can then sort by size.
Third-Party Freeware: To truly view and sort your entire folder tree dynamically, standard power-user practice is to download a lightweight tool like JAM Software’s TreeSize Free or MindGems Folder Size. Run these as an administrator to immediately see a visual, sorted list of every folder on your drive. macOS (Finder)
Mac computers have native support for calculating and sorting folder sizes directly within the default Apple Support Finder Guide. How to quickly find and delete large files on windows 11
