        Measure-Object |
        ForEach-Object { $_.Count }

    #select largest file in given directory
    Get-ChildItem -Recurse -File -ErrorAction SilentlyContinue -Force |
        Sort-Object Length -Descending |
        Select-Object -First 1

    #get average file size in a given directory
    Get-ChildItem -Recurse -File -ErrorAction SilentlyContinue -Force |
        Measure-Object -Property Length -Average …
