TreeSize Free 4.8 — What It Is and What It Does

TreeSize Free is a free disk space analysis utility for Windows that helps you see exactly where your storage space is being used. It scans drives and folders and shows you their sizes so you can quickly find what’s taking up the most room.

Key Features

• Folder & Subfolder Size Breakdown: Shows how much space each folder (and subfolder) occupies, down to individual files.
• Explorer-Style Interface: Navigate storage usage much like browsing folders in Windows Explorer.
• Visualization Tools: Includes treemap charts and colored bars to visually represent disk usage.
• Context Menu Integration: You can start a scan by right-clicking a drive or folder in Windows Explorer.
• Network & Cloud Support: Scans local drives as well as network shares and cloud-synced folders.
• Fast Scanning: Uses efficient methods (like Master File Table access on NTFS) for quick results.

The version most often referenced is 4.8.1.609, released in 2025, and it’s lightweight (around ~15–18 MB) and compatible with Windows 10 and 11.

What You Can Do With It

• Track down large files eating space on your drives.
• Identify forgotten media or old backups that are cluttering storage.
• Clean up efficiently by focusing on the biggest space hogs first.
• Explore hidden or unusual files that Windows Explorer doesn’t clearly show.

It’s especially useful when your disk seems full but you don’t know why — TreeSize can reveal hidden usage that Explorer may underreport.

Free vs. Paid (Optional Upgrade)

TreeSize Free covers the basics of finding and visualizing disk usage. Paid versions (Personal/Professional) add things like:

• Reporting and exporting
• Scheduled scans
• More advanced network scanning
• Larger environment support
  (These are part of the broader TreeSize product family.)

How It Works (Quick)

1. Install or run portable version.
2. Choose a drive or folder to scan.
3. Explore the size breakdown and charts.
4. Sort by size to see the biggest space users first
