When you have set up a hot folder, it will not start processing PDF documents immediately. You will first have to make it active. When activating a hot folder, you can also give it a specific priority level: low, medium or high. You may want to “turn off” a hot folder if you do not wish to use it temporarily, by making it inactive. It is also advisable to make a hot folder inactive while changing its settings.
