What is an LGM file?

LGM files mostly belong to LongoMatch. LGM files are LongoMatch project files used by the LongoMatch software for sports video analysis. They are stored in UTF-8, meaning the content is text-based and can be read by a text editor, although proper interpretation requires the LongoMatch application.

Project Settings: They store data such as match timelines, event markers, and configuration details.

Analysis Data: The file may include timestamps and annotations for sports video review.

FilExt.com notes: These files are designed specifically for managing project information in a video analysis workflow. To open and view an LGM file, use LongoMatch. Manual editing is not recommended unless you understand the structure, and keeping backups is a wise precaution.

How can I open an LGM file?

You need a suitable software like LongoMatch to open an LGM 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 LGM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a LGM file directly in the browser:.

LGM file format:

To view or edit LGM files you need to know the file format, because it determines how the data in this file is stored. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our analysis of the LGM files produces the following result:
