How do I find and delete all files without a file extension and delete them?

Question

I'm working with a recovery database that recovered data from a plex server. The data produced thousands of files with a GUID name without an extension. I want to just wipe all these files out and delete the subfolders.

Here's a script to start with.

$path = "c:\temp\zzzz"
$files = Get-ChildItem -Path $path -File -Recurse | Where-Object -Property Extension -eq ""
"We found {0} files." -f $files.count
$files | Remove-Item -whatif
$dirs = Get-ChildItem -Path $path -Directory -Recurse | Sort-Object -Property Fullname -Descending   # process subfolders first
foreach ($dir in $dirs) {
    $dir.FullName
    $contents = Get-ChildItem $dir.FullName
    if ($contents.count -eq 0) {                  # delete empty folders 
        $dir.FullName
        $dir | Remove-Item -WhatIf
    }
}
