FolderSizes vs SpaceMonger

FolderSizes is a Windows tool for examining file and folder space across local and network storage. It scans local drives, external drives, mapped network drives, UNC paths, and network shares, then presents results as treemap, sunburst, bar, and pie charts. Searches can be narrowed by age, name, attributes, size, owner, date, or depth-related criteria. Reports export to Excel, PDF, HTML, CSV, and XML; recurring scans can also send automated email reports. Disk and folder usage tracking, along with file system snapshots, can show changes over time. The free edition has no time limit and includes four visualizations, reports, advanced search, and scan filtering. The free trial has no feature limitations. A Personal Edition license costs $30 as a one-time purchase and is limited to personal and home network use; a Single-User Pro license costs $60 as a one-time purchase. Pro upgrades include priority technical support and free minor version upgrades. The maker says FolderSizes has been continuously developed since 2003.

SpaceMonger is a Windows utility for finding and managing storage on PCs and shared networks. It scans and maps files and folders, then displays storage in a treemap to help identify large items. A file-type breakdown and flexible search by size, type, or custom criteria can narrow what to review. Users can build changing cleanup lists and copy, move, or delete files from them. SpaceMonger does not include application sizes in its storage view. Its listed system requirements cover Windows 2000, XP, Vista, 7, 8, 8.1, and 10. The purchase page lists English and Spanish as included languages and 30 days of support. The software is paid, has a 30-day trial, and has no free plan. Stardock says it has operated as a software development company since 1991 and specializes in Windows desktop customization and productivity software.
