.PRM File

The prm file extension is associated with the TomTom GPS devices and GPS navigation software.

The prm files store complete maps with roads, towns, cities, villages etc. used to navigate users to destinations.

How to open:

Use TomTom Navigator to work with *.prm files.

How to convert:

As far as we know, this .prm file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
