First, open the AutoDrive User Interface (Left CTRL + Left ALT + KeyPad 0), then change the option to YES for Use Folders, then click on apply.
Once you have done this, go back to the AutoDrive panel and turn on edit mode. Now, in the drop down menu you should see a ‘+’ sign; click on the plus sign and a menu will show up to name your folder.
To add a route to your folder, click on the route (the menu will roll back up), re-open the drop down menu and click on the sideways arrow (pointing to the right) next to the folder to add the route. Continue this process to add more routes or more folders.
