NTFS Permissions Auditor is a Windows desktop application that scans your file servers and shows exactly who has access to what. It reads the NTFS access control lists (ACLs) on every folder you point it at and presents the results in two views: a folder hierarchy view (which folders does each permission apply to?) and an account view (which folders can each user or group access?).
The tool is designed for IT administrators, security teams, and compliance officers who need to verify file permissions without writing PowerShell scripts or manually clicking through folder properties. You create an audit profile, add your directories or network shares, run the audit, and get a complete permissions map.
This manual covers version 26.3.20 running on .NET 10.
