# FolderSizes > FolderSizes is a fast, network-enabled disk space analyzer and folder size tool for Windows from Key Metric Software. It reports folder sizes; finds large, old, duplicate, empty, and temporary files; and visualizes storage with treemap, sunburst, bar, and pie charts. A free edition with no time limit is available; the Pro edition adds export, scheduling, trend analysis, snapshots, and a command-line interface. FolderSizes runs on Windows 11, 10, 8, and 7 SP1 and on Windows Server 2025, 2022, 2019, 2016, and 2012 R2 (64-bit). It scans local drives, mapped network drives, UNC paths, and network shares, and supports NTFS, FAT32, exFAT, and cloud-synced folders. It is used by IT administrators managing server storage, business users tracking disk space, network administrators monitoring shared drives, and home users cleaning up personal computers. Common use cases: finding what is consuming disk space on servers, identifying files to archive or delete, monitoring storage growth over time, enforcing file retention policies, preparing for storage migrations, optimizing backup schedules, managing network share quotas, and cleaning up user profiles. Key differentiators: a modern interface with dark and light themes, a multi-threaded scanning engine, 13 file report types, four chart types, report scheduling with email delivery, file system snapshots, a command-line interface, regular updates, and a lifetime license option.
