You can edit an existing hot folder by selecting it in the list of hot
folders and clicking the 
button, or by double clicking an existing hot folder
in the list. This will open the Hot Folder Editor. For more information
on the individual settings to be made, see Setting up Hot Folders.
It is recommended to disable hot folders during editing, because files that are in the input folder will continue to be processed with the old settings while the user is still editing the hot folder.
If you want to rename/delete subfolders of the input folder, disabling the hot folder is even mandatory.
