Read a directory listing into Powershell, then display every other filename to the screen

Here is the Powershell script that I have created so far: 

dir C:\Windows\System32 | Sort-Object -Descending

My end goal is to list all the files (files only - no sub directories) in the following directory, sorted by filename in descending order. Next I need to read this directory listing created into Powershell, then display every other filename to the screen.

I was trying to find a way to do this by piping the sorted results into the Foreach-Object cmdlet, and then reading "Object" from the resulting list, using the Get-Content cmdlet, and the FullName proprety of each object - like: Get-Content $_.FullName 

dir C:\Windows\System32 | Sort-Object -Descending | ForEach-Object

Any ideas how to make this happen with those cmdlets?

you can get the index number of an item in an array with .IndexOf(). you can get the even numbers of a list of numbers by using "mod 2 = zero". something like this ... 

$TargetDir = "$env:windir\system32"

$FileList = Get-ChildItem -LiteralPath $TargetDir -File |
    Sort-Object -Property Name

foreach ($FL_Item in $FileList)
    {
    # if "number mod 2 = zero", then it's an even number
    if ($FileList.IndexOf($FL_Item) % 2 -eq 0)
        {
        $FL_Item.Name
        }
    }
