What is a .rm file?
A .rm file is a RealMedia. This one is a specialist format without an obvious everyday home.
How to open a .rm file
- The program that created it is by far the most reliable way to open it.
- On Windows, use a hex viewer or the free TrID tool to identify what the file really is.
- On Mac or Linux, running `file yourfile` in the terminal identifies most formats instantly.
The registry records this extension against RealMedia, so software from that family is the most likely match.
How to convert a .rm file
- Identify the file first, then look for an export or Save As option in whatever program can read it.
MIME type
When a .rm file travels over the web, servers label it with this MIME type:
application/vnd.rn-realmediaThe technical record
For archivists, developers and the merely curious: these are the PRONOM registry entries for .rm.
| Format name | Version | MIME type | PUID |
