About Folder Size
Overview
Folder Size from MindGems fills the gap Windows Explorer never fixed: it shows the size of every folder and subfolder at once, sorts them, and adds bar and pie charts for a visual read of your drive.
Key Functionality
It scans local drives, USB sticks, NAS boxes and network shares, and can reveal the sizes of system and hidden folders that Windows keeps out of sight. Right-click integration analyzes any folder straight from Explorer.
Reports and Automation
Results sort by size, date, owner and more, with built-in reports for the largest and oldest files and folders. Exports go to Excel, CSV or XML, and a command line mode allows scheduled scans. The tool installs no services or shell hooks, so it costs nothing when idle.
Use Cases
For a straightforward folder-size view with charts, and for tracking down space that seems to vanish into hidden system folders.
