Treesize V7.1.5 May 2026

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.

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. treesize v7.1.5

The duplicate search engine in 7.1.5 now uses byte-for-byte verification alongside SHA-256 hashing. It also introduces a "Smart Selection" feature that automatically selects duplicates older than X days for deletion, saving you from clicking through hundreds of checkboxes.

Unlike previous versions that struggled with network latency, TreeSize v7.1.5 includes enhanced scanning algorithms for Network Attached Storage (NAS) and mapped drives. It supports parallel scanning, drastically reducing the time needed to audit a 10TB RAID array. You can save scan profiles for specific servers, allowing for automated weekly snapshots.

| Feature | TreeSize v7.1.5 | WizTree | WinDirStat | | :--- | :--- | :--- | :--- | | Speed | Very Fast (MFT scan) | Fastest (reads MFT) | Very Slow | | NAS Support | Excellent (v7.1.5 optimized) | Poor (requires local scan) | Poor | | Export Reports | Yes (Excel/HTML/XML) | No | No | | CLI Scripting | Yes | No | No | | Dark Mode | Yes (fixed in v7.1.5) | Beta | No |

While WizTree is faster for local NTFS drives because it reads the Master File Table (MFT) directly, TreeSize v7.1.5 wins for network, cloud, and detailed management. TreeSize v7

Note: TreeSize v7.1.5 does not support Windows 7 or 8.1. Use version 6.x for older OS.
