Disk Space Analyzer review
A Mac-focused analyzer for visualizing, managing, and reporting storage across many volume types.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Disk Space Analyzer is a macOS utility from Nektony for users who need to understand storage usage and locate large files or folders. It scans internal, external, removable, network, cloud, and mounted volumes, then presents results through sunburst and folder-treemap visualizations. A largest-files and folders list, hidden-item detection, purgeable-space display, and file-name search help narrow attention to specific storage areas. Users can also copy, move, or remove files and folders from scan results.
The product follows a freemium model with a free version and in-app purchases, while the vendor download page describes a two-day full-featured trial. Paid options include Pro Mode Monthly Subscription, Pro Mode Annual Subscription, and Pro Mode Lifetime License. The plans add Pro features, with the lifetime option providing a lifetime license. This gives occasional users a free starting point and offers recurring or one-time paths for users who need the paid feature set.
Its strongest fit is storage analysis across more than the Mac's internal drive. Dropbox and Google Drive are named integrations, and the ability to scan network, cloud, removable, and mounted volumes makes it relevant for people managing files across several locations. CSV export supports reporting outside the app, while cleanup actions keep analysis connected to file management. Users seeking a Mac utility with visual storage maps and wide volume coverage should consider it. Those needing a non-macOS platform should choose another tool.
