Need to copy single file to all subfolders recursively

Question

Please can someone help me create a powershell or CMD script, as simple as possible (1 line?) that will do the following...

-Take file (c:\test.txt) -Copy to ALL subfolders within a given folder, including multiple levels deep eg, c:\test1\1\2\3\ and c:\test2\6\7\8\ -Without overwriting that file if it already exists -Not changing ANY existing files. Just adding the original txt file if it doesn't exist.

I've tried a bunch of scripts I found online, changing them, but have been unsuccessful. Either it overwrites existing files, or doesn't go multiple levels deep, or skips all the folders between top/bottom levels, or throws errors. I give up.

Thanks Matt

How about something like this...

$folders = Get-ChildItem -Recurse -Path C:\temp\1 -Directory
$file = "c:\temp\test.txt"

foreach($folder in $folders){
    $checkFile = $folder.FullName + "\test.txt"
    $testForFile=Test-Path -Path $checkFile
    if(!$testForFile){
        Copy-Item $file -Destination $folder.FullName
    }  
}
