Answer

$MainDir = "/path_to_dir/MainFolder"

function MainScript {
    Write-Output "Start Script"
    if ($MainDir -notmatch '/$') {
        $MainDir = "$MainDir/"
    }
    $mainDirs = Get-ChildItem -Path $MainDir -Directory
    $fileListResult = New-Object Collections.Generic.List[String]

    foreach ($dir in $mainDirs) {
        $fileListRaw = Get-ChildItem -Path "$mainDir$dir" -File -Recurse
        $fileCount = ($fileListRaw  | Measure-Object).Count
        Write-Output "Main Directory '$dir' has total files: $fileCount"
        foreach ($file in $fileListRaw) {
    
            $fileListResult.Add($file.FullName)
        }
    }

    Write-Output "`nList of files found:"
    foreach ($file in $fileListResult) {
        Write-Output "$file"
    }
    Write-Output "End Script"
    read-host “Press ENTER to continue...”
}
