File Flipper is a design file converter that allows users to convert design data between the Trimble GCS900 and Trimble Earthworks file and folder structure. File Flipper also allows to import single design, calibration and geoid files and put those files into the correct folder structure in order to use them with the Trimble GCS900 or Trimble Earthworks Machine Control software. Trimble File Flipper will run on the TD520 display as well as third-party tablets and phones running Android 5 and above.
