What is an M00 file

M00 files mostly belong to Leica Geo Office. M00 files are used by Topcon GNSS receivers to save collected survey data.
This file stores geospatial readings such as coordinates, time stamps, and satellite tracking data.
Key details summarized by FilExt.com:

Primary use: Logging raw data from GNSS field measurements

Secondary use: Facilitating data processing in survey software

The data is handled by programs including Leica Geo Office which processes GNSS information.
FilExt.com note: Some devices may output multiple related files (for example, M00 paired with .M01) to represent different parts of a complete survey session.

How to open an M00 file

You need a suitable software like Leica Geo Office to open an M00 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 M00 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a M00 file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert M00 files:

Leica Geo Office
See the previous paragraphs to learn more about the main application. M00 files are often referred to as Leica Geo Office data files because this type of file is primarily created or used by this software.
Topcon Magnet Office, other GNSS processing software
An M00 file is a raw data file created by a Topcon GNSS receiver. It stores the raw Global Navigation Satellite System (GNSS) data collected by the receiver during a survey. This data includes information from various satellite constellations, such as GPS, GLONASS, Galileo, and BeiDou. The M00 file contains the pseudorange, carrier phase, and Doppler measurements, as well as other relevant information like time stamps and satellite ephemeris data. This raw data is essential for post-processing and analysis using specialized software like Topcon's Magnet Office or other compatible GNSS processing software. The M00 file format is proprietary to Topcon and is designed to be efficient for storing large amounts of high-precision GNSS data. The data within the M00 file is typically converted into other formats, such as RINEX, for further analysis and integration with other geospatial data. This file format is classified as GIS/Mapping File.

How to solve problems with M00 files

Associate the M00 file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest M00 file format. Search, therefore, e.g. on the manufacturer website after an available Leica Geo Office update.
To make sure that your M00 file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
