.FLT File Extension

3D scene description file created in the OpenFlight format; saves data in a hierarchical structure and and describes how to render a 3D scene for a real-time image generator; often used for military, urban city, and flight simulation visualizations.

The OpenFlight format is developed and maintained by Presagis (formerly MultiGen-Paradigm). It has been widely adopted as the standard format in the 3D visual simulation community. Applications such as 3ds Max and Blender provide native support for the file type.

Audio filter used for applying effects, such as reverb, echo, chorus, distortion, and other effects to an audio file; must be saved within the main application folder in order to be loaded by the program.

Most FLT files work with both Syntrillium Software Cool Edit Pro and Adobe Audition. Adobe acquired the assets of Syntrillium Software in May 2003 and introduced Adobe Audition in August 2003.

Flight saved by Microsoft Flight Simulator, a realistic Flight Simulation game; may be a flight included with the program or a flight saved in progress, which can be loaded and continued at a later time.

NOTE: The file "Fltsim.flt" located in Flights\Other\Fltsim.flt must be present in order for the program to open. If the file is removed, the Flight Simulator program may need to be reinstalled.

Graphics filter used to apply color correction, artistic effects, image distortions, or other modifications to an image; may be loaded and used by several different graphics programs.

NOTE: Some FLT files are only compatible with specific programs, so not all FLT files will be compatible with each application listed below.

Settings file used by E-on Vue, a program used to model 3D environments; contains a color filter curve that is generated using "keypoints" in a 2D grid; helps emphasize certain colors and filter out others when applied to a 3D scene material.
