What is a MES file?

MES files mostly belong to Datacolor Tools. MES files serve a variety of specialized purposes. They are most often used as color measurement data files by applications like Datacolor Tools and Color iMatch, where precise color data captured from instruments is stored.
They also work as XML message files used in Manufacturing Execution Systems, where data on production events and system messages is exchanged.
Other applications include:
  • Storing magnetic resonance spectrum data for systems such as Bruker TopSpin (Bruker).
  • Holding Siemens WinCC message data used in control systems.
  • Recording measurement information from instruments like the HP 4155A Semiconductor Parameter Analyzer.
  • Recording rail measurement data used in transportation research (UKM).
  • Containing text and configuration data for games (as seen in Neverwinter Nights; game support).
  • Serving as a mesh file for 3D modeling, such as in ANSYS simulations.
  • Occasionally, storing email message data in formats used by systems like Arachne.
  • FilExt.com note: The actual content and structure depend on the software that generated the file; some use XML for easy editing while others use a proprietary format. Using the proper application is key to opening and reading these files correctly.

    How to open MES files

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

    MES file format details:

    The file format determines how the data is stored in the file. 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. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Below is our analysis of the MES files:

    The MES file extension includes a lot of different file formats for different programs. But the following two file formats are common:

    All other MES files (82%) have no consistent format, frequently e.g. Source, From and MED. Sometimes used for scene, message, stat or auflage. You can get all the details of your MES file by dragging it onto this page or by clicking the button "Choose your .mes file to analyze" above.
