What is FLT file?

The file in the FLT format belongs to the 3D Image Files category. It was designed by Presagis. Additionally, the 3D Image Files category contains 622 of other files. OpenFlight Scene Description Format appears on 4 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on , Linux, Mac OS, Windows. It is recommended to use Blender to handle this file. This is a program created by Stichting Blender Foundation. Alternatively, you can use 6 other programs. The ArcGIS Desktop, 3ds Max, PolyTrans, FlightSIM programs will also handle the file when the Blender program does not fulfill its role.

How to open FLT file?

The most common problem when using OpenFlight Scene Description Format is that a specific FLT is not associated with the program. This causes the file FLT to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the FLT file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Blender

An often overlooked issue is to make sure that Blender is installed on the computer. To do this, enter the name Blender into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open FLT files.

Programs to open FLT file

Remember to download programs supporting FLT files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Blender with FLT files

However, it may happen that the application itself does not cause the FLT file to open in the Blender application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the FLT file with the Blender application.

Step 3. Update Blender to the latest version

The fault may also lie with the Blender program, it is possible that OpenFlight Scene Description Format requires a newer version of the program. In this case, use the Stichting Blender Foundation website or update the program from the application.

Step 4. Check for the following problems with the FLT file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This suggests truncating the FLT file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the FLT file that we want to open. As a result of the scan, sometimes it is not possible to recover FLT files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of FLT file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair FLT file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Presagis
When reading, a message appears that the file was encrypted or corrupted. The encrypted file FLT except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the FLT file to another location.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the FLT file again. Some anti-virus or backup software may occupy the FLT file for a certain period of time. If the problem persists, restart the machine.
