Horton’s Hints for FSX and Prepar3D


This installment of the long-running series of Horton’s Hints focuses on new installations of FSX and Prepar3D, and explains how to move various files, as well as pilot records to new installations. In view of Microsoft’s new Flight product being a geographically limited game and not the hoped for successor to FSX, we believe that FSX users will recognize that Lockheed Martin’s Prepar3D® is becoming the successor flight simulation product to FSX, particularly in view of expanded licensing alternatives and lower prices.

As sales of Windows 7 Home Premium are softening in view of the prospective release of Windows 8, we see many advertisements for Window 7 Professional and Ultimate versions as upgrades of Windows 7 Home Premium, and we take a look at those options in relation to operation of FSX and Prepar3D.


Moving Aircraft, Scenery, and Other Files from FSX to New Installations of FSX or Prepar3D


Prepar3D File Structure. The file structure of Prepar3D is completely parallel to FSX. For example, for Windows 7:

  • Aircraft files are contained in the (your Prepar3D location)SimObjectsAirplanes, folder.
  • Saved flights, and saved configuration files are contained in the “C:Users(Username)DocumentsPrepar3D Files” folder.
  • The Prepar3D user-modified Scenery.cfg file is contained in the “C:Documents and SettingsAll UsersLockheed MartinPrepar3D” folder.
  • The Prepar3D.CFG file, analogous to the FSX.CFG file, is contained in the “C:Documents and Settings(Username)Application DataLockheed MartinPrepar3D” folder.

Note that Windows 7 keeps up additional copies of some of these files in additional locations for protection.

Moving Aircraft and Scenery to new installations of FSX and Prepar3D. FSX aircraft and scenery products should be fully compatible with Prepar3D:

  • Aircraft container folders can be copied from FSX to their parallel locations in Prepar3D, such as SimObjectsAirplanes, SimObjectsRotorcraft, etc. You’ll find a new SimObjectsSubmersible folder in Prepar3D, which by default contains the “UnderwaterResearchLabSubmarine” folder.
  • FSX scenery can be moved to any location of your choice for Prepar3D, including remaining in its location for FSX. Generally, the only needed modification is to identify the scenery location in the Prepar3D Scenery Library Editor, which functions the same as in FSX, though the user interface is modified to be larger and more user friendly. In some cases, scenery and other products install other files and programs to protect licensing, and when this is true, product can most easily be installed in Prepar3D when the developer has included Prepar3D as an alternative location.
