Thanks for the quick response. I will need to test its behavior for lost connections.
Based on what I have discovered so far, I will have to create my own monitor. I need to create a list of new files from all of the monitored folders during each pass and then sort them by date/time to make sure they are processed in the correct order. It doesn't seem to notify about files that already exist. I will have to add this as well, although it is optional because it doesn't work correctly in my current system. Thank you, Patrick R.

If a file is not there because a network connection is broken, this will show up as a deleted file. YYMV since we do not test this use case in unit tests.
