Get-NTFSAcess and Get-NTFSEffectiveAccess are two cmdlets from the NTFSsecurity module.
Get-NTFSAcess retrieves the access rights on a folder or file. You can immediately who has what rights and from where the rights are inherited.
Get-NTFSEffectiveAccess by contrast shows the rights YOU (the account you’re using to access the data) have to a file or folder.
This is far superior to Get-Acl where you have to dig through several layers to get the information.
