What is an RMH file

RMH files mostly belong to Rights-managed HTML File by Microsoft Corporation. The Windows Rights Management Add-on for Internet Explorer 6 provides a way for users of supported Windows operating systems to view, but not alter, files with restricted permission. Those working on these files are using the text/rmh MIME type instead of application/octect-stream. The IANA, however, has no record of an approval for that MIME type.

How can I open an RMH file?

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