What is an HMS file?

HMS files mostly belong to HEC-HMS. There are two main uses for HMS files.:

HEC-HMS project files: These files are used in hydrologic simulation. They store a model's project configuration and simulation parameters for water-cycle studies. They are meant to be opened with HEC-HMS software and work within a proprietary setup that preserves the details needed for accurate modeling.

Human Measurement System files: In this case, the HMS file is actually a ZIP archive that holds measurement data. Such files often come from systems using measurement instruments and can be opened with any standard ZIP extraction tool or specialized software like GOM Inspect.

FilExt.com note: Review the details in your file to decide which use applies. The file content—whether it holds simulation parameters or compressed measurement data—will guide you on the proper opening tool.

How can I open an HMS file?

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