SizeTrend Professional
There is no separate Professional application to download and no second interface to learn. Entering a license key unlocks exports, network analysis, and scheduled scans in the same SizeTrend installation.
One-time license
$69.99
One-time purchase. No subscription. All future versions are included.
Built for repeated IT work
SizeTrend Free is designed to answer an immediate question: what is using this disk? Professional adds the tools needed when the same question must be answered repeatedly across workstations, servers, and shared storage.
Use Windows Task Scheduler to run SizeTrend even while you are logged off, keep only the latest snapshots, export HTML, Excel, or CSV reports automatically, and open past scans to see exactly what changed.
Already purchased? Open SizeTrend, select the Help ribbon, click Register, and enter the license key from your order.
