You can create a simple helper function called Get-Enum to list all the values in an enumeration:
function Get-Enum($name){ [Enum]::GetValues($name) | Select-Object @{n="Name"={$_}},@{n="Value"={$_.value__}} | format-table -autosize }
This will allow you to easily list all the values in any enumeration:
Get-Enum IO.FileAttributes
