What’s wrong with this code?

If the path is in the same drive as powershell script is it works even with spaces in the path
If the path is in a different drive it does not work if there are spaces in the path. If there are no spaces it works.

Script has a path passed as a first argument.

$param1=$args[0]
write-host "Given path is: " $param1

$rootPath = "$param1"

Get-ChildItem -Path "$rootPath" -Include RARBG.txt,RARBG_DO_NOT_MIRROR.exe -File -Recurse | foreach { $_.Delete()}



Get-ChildItem -Path "$rootPath" -Directory | ForEach-Object {
    $_.FullName
    $targetFolder = $_.FullName
    $targetFolder
    Get-ChildItem $targetFolder\*English*.srt | Move-Item -Destination $rootPath
}


Get-ChildItem -Path "$rootPath\" -Directory -Filter "Subs" | Remove-Item -Recurse -Confirm:$false -force
PAUSE
