title: Convert base64 string to file
body: <p>I'm trying to convert base64 strings back to the original files. The application from where I try to export these files will only allow me to export in base64 strings. This export returns the base64 string and the filetype.</p>
  
  <p>How can I convert these strings back to the original files? I've been trying things like this, but I don't think this will work with different types of files?</p>
  
  <pre><code>[System.Text.Encoding]::UTF8.GetString([System.Convert]::FromBase64String($file)) |
      Out-File C:\ID\document.$($extension)
  </code></pre>
  
  <p>Can anyone provide me some ideas on how to do this?</p>
