Overview
TreeSize Pro: See where your disk space goes
What is TreeSize Pro?
TreeSize Pro is a professional disk space analyzer and storage management tool for Windows. It helps you see exactly how disk space is used across drives, folders, and files—so you can locate space hogs, plan cleanup, and manage storage with confidence.
Whether you use it on a single PC, a workstation, or across business file servers and network shares, TreeSize Pro gives you detailed visibility into folder and file sizes, large files, duplicate data, and growth over time.
Built for IT administrators, consultants, and power users who need more than a basic folder size view: TreeSize Pro delivers the depth and control required for serious storage analysis and cleanup readiness.

Visual Analysis That Speeds Decisions
Charts, treemaps, and structured folder views turn raw size data into something you can act on. TreeSize Pro helps you spot the largest consumers of space at a glance—whether you prefer a treemap for proportional view, bar charts for ranking, or a classic tree view for drilling down.

How TreeSize Pro Compares
TreeSize Pro sits in the same category as other well-known disk space analyzers and storage tools. Where it stands out is in reporting depth, enterprise readiness, and workflow support. You get rich export options (PDF, Excel, HTML, XML, CSV), automation via command line and scheduled tasks, built-in duplicate file finding, and a focus on professional and IT workflows. If you need more than a one-off treemap—recurring reports, network and server scanning, or audit-friendly outputs—TreeSize Pro is built for that. Comparison is fair: evaluate feature set, performance, and support against your own requirements.
