File open: The workflow determines that transmission is complete when it can open the input file for a write operation.
None: No defined method is used to determine file completion. Transmission is complete as soon as the workflow detects the input file.
Trigger: The workflow determines that transmission is complete when it receives the trigger file for the input file. The Trigger pattern property controls how the workflow recognizes a trigger file. A trigger file must have the same name as the input file, with a different extension.
For files copied from an FTP server to a hot folder, set the Completion method property to Check size or Trigger.
