NTFSSecurity

[!IMPORTANT] NTFSSecurity will be archived soon. Please move to WindowsAccessControl, which is also on the PowerShell Gallery: Install-Module -Name WindowsAccessControl.

A PowerShell module for managing the permissions, audit settings, inheritance, and ownership of files and folders on NTFS volumes.

PowerShell offers only Get-Acl and Set-Acl; everything between reading and writing an access control list is up to you. NTFSSecurity closes this gap with cmdlets for everyday tasks, such as permission reports, adding or removing a single permission, repairing inheritance, and taking ownership.

Installation

Install the module from the PowerShell Gallery:

Install-Module -Name NTFSSecurity

You can also download a release from the releases page and install it without the PowerShell Gallery; see Installation.

The module runs on Windows in Windows PowerShell 5.1 and PowerShell 7.

Quick start

# Show the permissions of a folder
Get-NTFSAccess -Path C:\Data

# Give an account the Modify permission on a folder, its subfolders, and files
Add-NTFSAccess -Path C:\Data -Account 'CONTOSO\JohnDoe' -AccessRights Modify

# Remove the explicit permissions of that account again
Get-NTFSAccess -Path C:\Data -Account 'CONTOSO\JohnDoe' -ExcludeInherited |
    Remove-NTFSAccess

# List the explicit permissions in a folder tree, including long paths
Get-ChildItem2 -Path C:\Data -Recurse | Get-NTFSAccess -ExcludeInherited

Documentation

Read the documentation in the wiki, which is generated from the Docs folder, or in the folder itself:

• Overview: features, requirements, and the list of cmdlets
• Concepts: security descriptors, access rights, inheritance, privileges, long paths, and module settings
• Examples: common tasks
• Cmdlet reference: one page per cmdlet
• Contributor guide

The module author's tutorials from 2014 are still a good introduction, although some cmdlet names have changed since:

• NTFSSecurity Tutorial 1 - Getting, adding and removing permissions
• NTFSSecurity Tutorial 2 - Managing NTFS Inheritance and Using Privileges
