To create an SCS900 or Siteworks Controller in the Trimble Synchronizer Data Folder in your computer, you can either install the emulator and path it on start up for the first time to the Trimble Synchronizer Data folder, and it will create the Device Name and Trimble SCS900 Data Folders for you, or you can simply create the Folders for the device using File Explorer under the Trimble Synchronizer Data folder
\Trimble Synchronizer Data
\Device Name e.g. Alans PC
\Trimble SCS900 Data
Then the folder system for the Sites, Designs and Work Orders will be created by the controller software as you create those on the Device
