How to Compress an NTFS Folder with PowerShell

Yes, I am actually taking a few minutes to write a blog entry.  I was taking a year off but I'm having to much fun teaching my 90th PowerShell class right now.  Here is a quick and easy question.  "How do I compress a folder with PowerShell?" We have a target of E:\Mod01 .  Here is the command. Get-CimInstance -Query "SELECT * FROM CIM_Directory WHERE Name = 'E:\\Mod01'" |     Invoke-CimMethod -MethodName Compress The CIM_Directory class has all that we need.  The filter of 'E:\\Mod01' is not a typo.  We need to escape the backslash with another backslash.  This isolate the target so we do not compress other folders.  This object is passed to Invoke-CimMethod   where we call the Compress  method.  Nice and easy.  Remember to always verify that you are executing methods only against your intended target or really bad things can happen.
