Opening a BMT File

The BMT file type is primarily associated with FLIR Tools.

What is a BMT file?

BMT files mostly belong to FLIR Tools.

BMT files can be one of two main types. In many cases, they are thermal image files that use the JFIF structure (a common JPEG format) to store temperature data. This format is used by thermal imaging tools to embed temperature readings within a standard image file.

In other cases, a BMT file is used by games and simulations. These files may contain binary material data or act as containers for 3D models. They are found in applications like Assetto Corsa, TrackMania, or 9Dragons and require specialized tools such as BMT Viewer or JointMAX to open and process the embedded model information. For more on the gaming side, see the Assetto Corsa webpage.

Usage details:

If your file shows signs of a standard JPEG format with embedded thermal data, view it with image software that supports thermal metadata (often integrated in FLIR Tools).

If it appears to be a game or simulation file, use dedicated 3D or model viewing software.

How can I open a BMT file?

You need a suitable software like FLIR Tools to open a BMT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your BMT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BMT file directly in the browser:. Just drag the file onto this browser window and drop it.

BMT file format:

To view or edit BMT files you need to know the file format, because it determines how the data in this file is stored. The file format can be deduced from the file extension and the signature. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. Knowledge is power - this also applies when dealing with unknown or faulty files. Below is our analysis of the BMT files:

The BMT file type is a very commonly used file extension and includes different formats for different programs. But the following two file formats are common:

• 50% of all BMT files start with the bytes BM, which are crucial for this file format. These files contain neither text nor words, but only data. The average file size is 840 KB with most files being between 230 KB and 1 MB in size. This file type is based on cutting-edge technology.
• 40% of all BMT files save the data in JFIF file format. JFIF is short for JPEG File Interchange Format. It is a bitmap graphic that uses JPEG compression. They consist of illegible, cryptic characters. The average file size is 260 KB with most files being between 54 KB and 680 KB in size. Certain words are almost always found in the files, such as JFIF. A usual file name is IR20180601.BMT or SR20180601.BMT.

All the rest of the BMT files (10%) have different formats, often e.g. BLMY and JMXVBMT. If you want to find out which format your BMT file belongs to, just click on the button "Choose your .bmt file to analyze".
