TreeSize

TreeSize is a powerful and flexible utility for Windows that analyzes disk usage on local drives, network shares, cloud-backed storage and external devices. It reveals the size of folders and subfolders down to individual files and displays the data in intuitive visualizations like treemaps, bar charts, or pie charts. Users can quickly locate large files or directories, detect duplicate files, and perform bulk actions such as deletion, moving or renaming directly from the interface. Advanced search filters enable finding files by age, type, owner or other criteria. TreeSize supports export of scan results and storage reports to common formats (PDF, Excel, CSV, HTML) and, in its Professional edition, allows scheduling automated scans and reports — making it valuable for both individual cleanup tasks and ongoing storage management in business environments.
