A Folder Mapping Job works similar to a User Drive Mapping Job in that it is a master job which will create child sub jobs. It is different in that instead of creating jobs for each user it creates jobs for each folder contained in the source. For example if I have selected a folder as my source that contains 3 folders within it, the Folder Mapping job will create 1 child job for each of those folders. Additionally as new folders are created in the source folders, new child jobs will be created for them. 

Creating a Folder Mapping Job (Basics no advanced options)

1) In the Job Control section hit the "New Job" button and select "New Folder Mapping"

2) Select a source connector and folder (depending on what needs to be moved)

3) Select a Destination Folder 

4) Select a Job Type which all of the child jobs will have

5) Ensure that your Conflict Resolution and Delete Propagation are set properly

6) Hit OK
