Whereas the flow elements are used to perform processes, the connections (= the lines between flow elements) allow you to control the flow, i.e. to decide which files go where.
Example:
In the example below, the connections are configured to move the input files (based on their file type) to the correct Configurator element. Input that does not comply with one of the configured file types is moved to the “Other” folder and is (in this example) not processed.

If flow elements generate a report or log, i.e. indicate whether or not the input was processed successfully (with or without warnings), this information can be used to sort the resulting output.
Example:
In the following example, the first connection moves files that were preflighted successfully (green) or with warnings (yellow) to the Ok files folder, whereas the second connection moves erroneous files (red) to the Nok files folder.
