A flow (in its basic form) consists of the following elements:
- Some kind of input (can be files or folders) submitted to Switch
- One or more processes to be executed or tasks to be performed (e.g. renaming files, converting images, preflighting PDFs ...)
- Some kind of output (=processed files and/or folders)
Each of these elements is represented by a flow element, and the flow elements are interconnected via so called Connections (arrows). The direction indicates how the files will move (in this example from left to right).
