Treesize V7.1.5 Guide

tree is a command-line utility used to recursively list or display the contents of a directory in a tree-like format. The treesize command, often invoked as treesize, seems to be related but focused on reporting disk usage in a similar visual manner.

The specific version you're referring to is v7.1.5. Without specific details on what you need regarding the report from treesize v7.1.5, I will provide a general overview of how to use treesize and what kind of reports it can generate.

Why v7.1.5 Specifically? (The "Must-Update" Reason)

You might be asking, "I’m on 7.1.4. Do I need 7.1.5?" The answer is yes, especially for Windows 11 22H2 and 23H2 users.

Microsoft’s recent updates changed how the Recycle Bin and system volume information are reported. TreeSize v7.1.5 patches a critical issue where the tool could misreport "Free Space" on volumes larger than 4TB using the NTFS compression flag. In v7.1.4 and earlier, a 10TB volume might show 2TB of "Unknown" space. Version 7.1.5 correctly parses the new FSCTL_GET_VOLUME_BITMAP structures. treesize v7.1.5

Furthermore, v7.1.5 introduces full support for Windows 11’s Dev Drive (ReFS variant). Older versions would crash when scanning ReFS Dev Drives; 7.1.5 handles them gracefully.

Should You Upgrade from TreeSize 6.x or 7.0?

| Version | Pros | Cons | | :--- | :--- | :--- | | 6.x | Stable, works on old Windows | No cloud scanning, slow MFT, no dark mode | | 7.0 | Treemap, ribbon, cloud | Buggy memory handling | | 7.1.5 | All 7.0 features + stability + ReFS support | Requires .NET 6 |

Recommendation: If you use Windows 10/11, upgrade immediately. If you rely on command-line automation in a legacy Windows Server 2012 environment, stay on 6.x. tree is a command-line utility used to recursively

What is TreeSize? A Brief Overview

For those unfamiliar, TreeSize is a powerful utility that visualizes disk usage. Instead of staring at a bland list of folders in File Explorer, TreeSize renders an interactive treemap or detailed column view that immediately highlights the largest directories and files. Since the 1990s, it has been the gold standard for storage analytics.

TreeSize comes in two primary flavors:

• TreeSize Free: Quick, but limited to basic features and admin rights.
• TreeSize Personal / Professional: Paid versions with command-line support, duplicate file search, and export functions.

TreeSize v7.1.5 refers to the entire family, but this article focuses on the core engine shared by the Professional and Personal editions.
