Clear-Host
foreach($f in Get-ChildItem -Path $FileName -Recurse)
{
    if($f.Attributes -eq "Archive")
    {
        $OldName=$f.get_FullName()
        $NewName=$f.get_Directory().Name+"."+$f.Name.Split(".")[-2]+"."+$f.Name.Split(".")[-1]
        Rename-Item -Path $OldName -NewName $NewName
        write-host $OldName " --> " $NewName

    }
}
