In their own words
Folder Size
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.
LumaDisk
LumaDisk is a disk space analyzer for macOS and Windows that maps a filesystem to show what is using storage. Its interactive sunburst and treemap views update during a scan. The app groups regenerable developer folders such as node_modules, /target,.next, and DerivedData, and groups duplicate files with one copy selected to keep. It also lists files of at least 100 MB that have not been opened for six months, a year, or two years. External drives are fully supported; network volumes can be analyzed read-only. Cloud support includes iCloud Drive, OneDrive, and Dropbox, while Google Drive is described as coming soon. The free plan keeps scanning and the sunburst view available. A LumaDisk license is listed at $6.89 a month, billed as a one-time payment rather than a subscription, and covers up to five Macs. Requirements are macOS 12 or later on Apple Silicon, or Windows 10 or later on x86-64 or ARM64. Reclaim permanently deletes files, with a ten-second undo window and safeguards against queuing system folders.
