About RidNacs
Overview
RidNacs is a free disk space analyzer from SplashSoft that trades fancy visuals for a familiar file-manager layout: a tree view with a percentage bar column that makes large folders obvious without a treemap.
Key Functionality
It scans local and network drives quickly, reads the filesystem in the background with multi-threading, and lets you browse the tree while the scan is still running. Small files can be grouped under a configurable size threshold to keep the view clean, and the bar charts can be restyled with skins.
Reports and Explorer Integration
Results export as XML, HTML, CSV or plain text, so you can print them or compare scans over time. RidNacs also adds itself to the Windows Explorer context menu, so any folder can be analyzed with a right-click.
Use Cases
For people who prefer sorted lists and printable reports over visual maps, and for quick checks of network shares.
