Notes about the RMH file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The RMH file type is primarily associated with '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.
