Disk Usage Analyzer vs Folder Size

Disk Usage Analyzer is a free Linux desktop app for checking how storage is used and how much space remains. It scans selected folders, storage devices, and online accounts; external drive scans are also supported. Results present folder sizes in a tree view and a graphical representation, so users can inspect how a scan’s contents are distributed. The app page directs users to install the latest version from Flathub, which lists aarch64 and x86_64 architectures. The GNOME app page lists version 50.0, released on 2026-03-13, and names Paolo Borelli, Stefano Facchini, and Christopher Davis as maintainers. Users can report issues or suggest ideas through the app’s issue tracker. Flathub labels the app “Medium Risk.” The plan is listed at free. The app page does not identify which online account services can be scanned, and it does not state security certifications or compliance details.

Folder Size analyzes Windows storage to identify large files and folders and display disk usage in bar and pie charts. It scans local and external drives, USB and flash drives, SD cards, NAS, SAN, and network shares. A File Explorer right-click menu can start a scan of a folder and its subfolders. Results include lists such as largest, oldest, newest, empty, and longest-path items, with export to Excel, CSV, or XML. The application also lets users cut, copy, paste, delete, and move files or folders. Scan data can be saved and loaded later to compare results over time. The maker says scans run locally and data such as file names and folder sizes are not uploaded. A free plan is available. Personal costs 24.95 USD as a one-time fee for a license that never expires; Professional costs 39.95 USD as a one-time fee and adds command-line automation. The listed requirements include Windows 11, 10, 8.1, 8, 7, or Windows Server 2008 or newer, at least 1 GB RAM, and 10 MB of disk space. Folder Size cannot scan symbolic links.
