title: SecureBlackBox - does TElSimpleSFTPClient.UploadStream automatically create folders if they don't exist? How to suppress?
body: <p>I am working on a C# project that connects to an SFTP server to upload a file.  Which folder to upload to is a configurable setting.  If the folder doesn't exist, it should fail.</p>
  
  <p>However, I have been informed that, instead of failing, it is automatically creating the folder on the SFTP server.  There's no 'create a folder' logic in either my code or the in-house library wrapper.  Is it something that SecureBlackBox does, and if so then is there any way I can suppress this behaviour?  Or is it down to the SFTP server setup?</p>
