Powershell find and move password protected PDF files

I'm working on a script to identify password protected pdf files in a folder. If the pdf is password protected then it will move the folder and all files and sub folders to another folder. I can get the script to work correctly with a copy but it appears the streamreader that is reading the files for "Encrypt" is locking the files preventing me from moving the files. I've been trying to work on a way to close streamreader but so far nothing has worked. Any help would be greatly appreciated.

$Source = 'sourcefolder'
$Dest = 'Destinationfolder'
        
Get-ChildItem -Path $Source -Directory |
ForEach-Object {
    If (Get-ChildItem -Path $_.FullName -filter *.pdf | where { 
            $_.OpenText().ReadToEnd().Contains("Encrypt") -eq $true }) {
        
        Move-Item -Path $_.FullName -Destination $Dest -Force -Verbose
    }
}

You need to dispose of the stream reader before leaving the Where-Object block:

... |Where {
  try {
    ($reader = $_.OpenText()).ReadToEnd().Contains("Encrypt")
  }
  finally {
    if($reader){ $reader.Dispose() }
  }
}

In the context of your existing script:

Get-ChildItem -Path $Source -Directory | ForEach-Object {
  if (Get-ChildItem -Path $_.FullName -filter *.pdf | Where-Object { 
      try {
        ($reader = $_.OpenText()).ReadToEnd().Contains("Encrypt")
      }
      finally {
        if ($reader) { $reader.Dispose() }
      }
    }) {
        
    Move-Item -Path $_.FullName -Destination $Dest -Force -Verbose
  }
}
