I'm trying the "Folder sensor". I want to make sure that a folder is empty. I cannot see a way to not count hiden files like Thumbs.db. At this point I cannot use the default sensor, it does not fit my needs. Why isn't there a setting to allow to not scan hidden files ? :-( It seems to me really basic setting.
https://www.paessler.com/manuals/prtg/folder_sensor "The Folder sensor counts all files in a folder, including hidden files."
I suppose I'll have to write my own script?
