PowerShell Help

Hi
I am wanting to get a list of extensions in a folder, but exclude a list of known extension that are stored in a text file(one per line). Using the following code:

$Exclude = Get-Content C:\Scripts\ExcludeExt.txt

Get-Childitem -Recurse |

Where-Object { (-not $.PSIsContainer) -and ($Exclude -notcontains $.Extension) }

but get a lot of errors

You must provide a value expression following the ‘-notcontains’ operator.

I’m really not sure what is wrong with my statement.

Please ignore, should be { (-not $.PSIsContainer) -and ($Exclude -notcontains $.Extension) }

Keep in mind if you are using PS v3 or later you can simplify your where-object block.

$Exclude = Get-Content C:\Ephemeral\ExcludeExt.txt
Get-ChildItem -File -Recurse | where { $PSItem.Extension -notin $Exclude }
