Adds a Saturn property to files that contains directory + basename (no extension). Example with some previous filtering by extension type and name match.
$file = Get-ChildItem .\UFS |
where {$_.Extension -eq ".ufs"} |
where {$_.Name -match "Iter3"} |
ForEach-Object {$_ | Add-Member -type NoteProperty -Name Saturn -Value ($_.DirectoryName + "\" + $_.BaseName) -PassThru}
