What is a CGL file?

CGL files mostly belong to Microsoft Flight Simulator. This file extension is used in several fields, each with its own internal format and purpose.
Main Uses:

Microsoft Flight Simulator Data: Stores simulation information and graphics instructions. Often linked with a computer graphics library approach. More details can be found at Flight Simulator.

CogLab Experiment Data: Contains experiment result data encoded in Java. Visit CogLab Info for more information.

Compressed Video: Encapsulates video streams in an MP4 container. VLC Media Player can play these files. Check out VLC Media Player for support.

PNG Image Data: May hold PNG images used as Canon Camera Image Files, viewable with tools like CGL Viewer.

Functionality:
This file is a container that does not follow a single standard. Its internal structure may be set for simulation data, experimental results, video containers, or image files. The actual content depends on the application that created it.
Usage Tips:
FilExt.com tip: If you encounter issues opening a CGL file, inspect its binary signature with a file viewer or hex editor. Align the software tool you use (such as Microsoft Flight Simulator, a Java-based application, VLC Media Player, or an image viewer) with the file’s internal format.

How to open CGL files

You need a suitable software like Microsoft Flight Simulator to open a CGL 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.

CGL file format:

The file format determines how the data is stored in the file. The file format can be deduced from the file extension and the signature. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below is our analysis of the CGL files:

The CGL file extension is rarely used and is used by different programs with different formats. The following file formats are most commonly found in CGL files:

• 45% of all CGL files use the same file format, which can be identified by the letters "FBsA" at the beginning. If you open these files in a text editor, you will see only illegible characters. CGL files can be up to 2 GB in size, but are often around 1 KB - 1 GB. This file type is new and state-of-the-art. The files contain the following words: FBsA. An example of a file name is WaterBlurMasks.cgl or sai221.cgl. Such files are related to masks, water, bldn and blur.
• 20% of all CGL files internally utilize the Java file format. This format is used to save Java objects to a file (ex. save game state as file) via object serialization. Such a Java object may contain functions and data like settings, images or videos. These files are binary files, so they do not contain text, but only cryptic characters. CGL files can be up to 24 KB in size, but are often around 3 KB - 10 KB. Certain words are almost always found in the files, such as CLResults, FirstNamet, LCLSummary;[, LabNameq, LastNameq, Ljava/lang/String;L, Summaryt, TBTHeaderst, PlotUpdatedZ, SavedAsCogLabDataI, numZ, saveGlobalI, versionIndexL, CLHDt, HTMLUpdatedI, LCLHTMLData;L, TBTS, [Ljava/lang/String;L and numL. These files are attributed to effect, memory, asymmetry, stroop and brain, and nearly always contain personal information.

All the rest of the CGL files (35%) have different formats, the following 3 formats exist: MP4. Tagged as thumb. If you want to find out which format your CGL file belongs to, just click on the button "Choose your .cgl file to analyze".
