In their own words
FolderSizes
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.
