What is a MET file?
A .MET file is a data container used by various software applications. Because the extension is a common abbreviation for "metadata" or "meteorological", several different programs use it for entirely different purposes. For example, a .MET file is often an eMule Resource File used by the eMule peer-to-peer client to track file downloads and server lists.
In scientific and engineering fields, .MET files contain meteorological weather data used by simulation software like PVsyst and EnergyPlus. Other uses include method files for Agilent chromatography software, map calibration files for OziExplorer, and general metadata for games like Dragon Age or platforms like Instagram. Because .MET has multiple possible meanings, we recommend using viewer.online/met to identify the actual format of your file. viewer.online/met analyzes .MET files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
How to open MET files?
The correct software depends entirely on the file's internal structure. If it is an eMule Resource File, you need the eMule client. If it contains weather data, you must load it into PVsyst or a compatible building simulation tool. Some .MET files are plain text, XML, or JSON formats that you can inspect using a basic text editor or command-line tools.
If you need to change the file into a more common format, we recommend file conversion to sensible target formats on convert.guru. Depending on the specific data inside, text-based .MET files can often be converted to .CSV, .JSON, or .TXT.
Summary
viewer.online/met directly opens and previews .MET files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
