Folder Permission details for folders\sub folders

Question

I want to extract a folder and its sub folders permission details.

My server is Windows 2008, I use Windows PowerShell script but getting below error.

Get-ChildItem : A parameter cannot be found that matches parameter name 'Directory'.
At line:1 char:5
+ dir -Directory -Path "H:\RMSRE7\RMS1" -Recurse -Force
+     ~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Get-ChildItem], ParameterBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand

PowerShell script:

$FolderPath = dir -Directory -Path "\\H:\RMSRE7" -Recurse -Force
$Report = @()
foreach ($Folder in $FolderPath) {
    $Acl = Get-Acl -Path $Folder.FullName
    foreach ($Access in $acl.Access) {
        $Properties = [ordered]@{
            'FolderName'       = $Folder.FullName;
            'AD Group or User' = $Access.IdentityReference;
            'Permissions'      = $Access.FileSystemRights;
            'Inherited'        = $Access.IsInherited
        }
        $Report += New-Object -TypeName PSObject -Property $Properties
    }
}
$Report | Export-Csv -Path "D:\Public\RE7_FolderPermissions.csv"

Which version of PowerShell? -Directory and -File are not part of the filesystem provider in early versions - not sure exactly when they were introduced, but probably v3. — boxdog
Correct. The parameters were added with version 3, so the OP is most likely running PowerShell v2. — Ansgar Wiechers

In PowerShell v2 (which is what you seem to be using) the Get-ChildItem cmdlet doesn't have a parameter -Directory. That was introduced with PowerShell v3.

If you want to restrict the results of Get-ChildItem to directories you need to use a Where-Object filter prior to PowerShell v3, e.g.:

$FolderPath = Get-ChildItem -Path "\\H:\RMSRE7" -Recurse -Force |
              Where-Object { $_.PSIsContainer }

The [ordered] type accelerator also isn't available prior to PowerShell v3, so you need to remove it from your code.

$Properties = [ordered]@{
    'FolderName'       = $Folder.FullName;
    'AD Group or User' = $Access.IdentityReference;
    'Permissions'      = $Access.FileSystemRights;
    'Inherited'        = $Access.IsInherited
}

If you want to ensure a particular order of fields in the output CSV you can pipe the data through Select-Object before the export. And you may want to add the parameter -NoType to Export-Csv to avoid the object type comment at the beginning of the output file.

$Report |
    Select-Object FolderName, 'AD Group or User', Permissions, Inherited |
    Export-Csv -Path "D:\Public\RE7_FolderPermissions.csv" -NoType
