### Get-NTFSAccess
Returns a list of all access control entries found on the given object(s).

    #Get permissions from all files or folders in the current folder
    dir | Get-NTFSAccess

    #to read the permissions of a specific file
    Get-NTFSAccess -Path C:\Windows

#### Get permissions from all files or folders in the current folder

    dir | Get-NTFSAccess

#### To read and also remove only the explicitly assigned ones

    dir | Get-NTFSAccess -ExcludeInherited | Remove-NTFSAccess

The pipeline support can also be used to backup and restore permissions of one or many items:
PowerShell

#### To backup permissions just pipe what Get-NTFSAccess returns to Export-Csv

    dir | Get-NTFSAccess -ExcludeInherited | Export-Csv permissions.csv

#### To retore the permissions pipe the imported data to Get-NTFSAccess

As the imported data also contains the path you do not need to specify the item

    Import-Csv .\permissions.csv | Get-NTFSAccess

All cmdlets can handle SIDs and also SamAccountNames. The output contains always both unless a SID is not resolvable.
The types.ps1xml file is extending the common objects with some useful information and the format.ps1xml file formats all the output in almost the same way like the Get-ChildItem output.

By implementing the [Process Privilege http://processprivileges.codeplex.com/] project the cmdlets can activate the required privileges for setting the ownership for example.


# Add-NTFSAccess
Adds a specific ace to the current object. This can be done in just one line:

     Get-Item .\VMWare | Add-NTFSAccess -Account Contoso\JohnD -AccessRights FullControl

# Get-NTFSAccess

Gives you a list of all permissions . normally you are interested not in the inherited permissions so the switch ExcludeInherited can be useful

    Get-Item F:\backup | Get-NTFSAccess –ExcludeInherited


## Filtering works with Where-Object

    Get-Item F:\backup | Get-NTFSAccess | Where-Object { $_.ID -like "*users*" }

# Get-NTFS Orphaned  Access

Lists all permissions that can no longer be resolved. This normally happens if the account is no longer available so the permissions show up as a SID and not as an account name.

To remove all non-resolvable or orphaned permissions you can use the following line. But be very careful with that as maybe the account is not resolvable due to a network problem.

    dir -Recurse | Get-NTFSOrphanedAccess | Remove-NTFSAccess

# Remove- NTFSAccess

Removes the permission for a certain account. As the pipeline is supported it takes also
ACEs coming from Get-NTFSAccess or Get-NTFSOrphanedAccess


# Get-NTFSEffectiveAccess

Shows the permissions an account actually has on a file or folder. If no parameter is specified it shows the effective permissions for the current user. However you can supply a user by using the SID or account name
PowerShell

    Get-Item F:\backup | Get-NTFSEffectiveAccess -Account S-1-5-32-545

# Get-NTFSInheritance
Shows if inheritance is blocked

# Enable-NTFSInheritance
It can be a problem if certain files or folders on a volume have inheritance disabled. Making sure that inheritance is enabled can be done using this cmdlets:

    Get-Item .\Data -Recurse | Enable-NTFSAccessInheritance

# Disable-NTFSInheritance
See Enable-NTFSInheritance

# Get-NTFSOwner
Shows the owner of a file or folder

    dir -Recurse | Get-NTFSOwner

# Set-NTFSOwner
Sets the owner to a specific account like:

    Get-Item .\Data | Set-NTFSOwner -Account builtin\administrators
