What is an HSM file?

HSM files mostly belong to Design Studio. HSM files are not tied to one single application. They are project data containers that hold structured content. The internal format varies with each use, so the file's purpose is defined by the software that created it.
Primary Application – HVAC System Files:
  • Used by Design Studio for HVAC projects. These files use a ZIP archive format to store system configurations and design parameters. They are sometimes known as Gira Project files and relate to ABB i-bus® Tool.
  • Other Use Cases:
  • Hypnospace Music File: In Hypnospace Outlaw, the HSM file holds music data formatted in JSON. More details are available at the official Hypnospace site.
  • Hit Sound Machine File: In The Sims 4, these files manage in-game audio data. They are also linked to Hitman Sound Mission files in Age of Empires II: HD Edition.
  • Help & Manual File: These files compile help documentation and work similarly to HTML Help Workshop files. Visit the Help & Manual website for further information.
  • Heroscape Map File: Used by Heroscape Master and in Age of Empires III scenarios, these files store map and scenario data. Additional insights can be found on the Heroscape site.
  • FilExt.com note: Each HSM file is meant to be opened with the software that created it because its structure—be it a compressed archive, a JSON document, or another format—reflects its project-specific data.

    How to open HSM files

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