foreach ($file in $files)

{
$file.FullName
*$file.FullName | Rename-Item -NewName {$_ -replace '_*(\[.*?\]|\(.*?\))_*' -replace '_+', ' '} $NewName
*Rename-Item -NewName {$_ -replace '_*(\[.*?\]|\(.*?\))_*' -replace '_+', ' '} 
*$NewName = rename-item $file.FullName.Replace('_*(\[*?\]|\(*?\))_*', '')
Rename-Item -Path $file.fullName -NewName {$_ -replace '_*(\[.*?\]|\(.*?\))_*' -replace '_+', ' '}
