-&future_feature+You can have WinSCP [[guide_automation#generating|generate a code template]] for ''Session.GetFiles'' for you. 
 + 
 +The method is quite powerful, but due to a wide range of it uses, its syntax can be cumbersome initially. For specific tasks, consider using convenient alternatives: [[library_session_getfilestodirectory|''Session.GetFilesToDirectory'']] and [[library_session_getfiletodirectory|''Session.GetFileToDirectory'']].
