For example if you scan a 15 page document to pdf, combine to one, no subfolder is created. If you scan a 15 page document to pdf, set combine to no, it creates 15 folders with one scanned page in each folder.
Loggining into our printer Apps/Scan to/my folder is set to none.
I have this set up and working to scan to contact as a pdf, but by default it is creating a subfolder for each scan. I found the setting before and shut if off for each user, but I have created a new user and I can't remember where the setting is.
