Uploading .GWD files?

Can FaceTime be used to upload .GWD files to the gear S3?

  1. What is “FaceTime”?

  2. What are “.GWD” files?

Facer doesn’t use any file transfer based system.

Looks like .GWD are project files for Gear Watch Designer. Only .PNG and .JPG image files can be used I believe. So .GWD are out.
