What is an RMA file?
An RMA file is a license file used by the RealNetworks Rhapsody music store, player, and subscription service. Rhapsody uses RMA files to verify that a user is authorized to play music files.
When a Rhapsody user attempts to play a song, Rhapsody uses an RMA file to check whether the user's computer is authorized to play that song. This is how Rhapsody performs Digital Rights Management (DRM). Rhapsody's DRM also prevents users from sharing downloaded music with others.
NOTE: In 2016, RealNetworks rebranded Rhapsody as Napster. It is unknown whether Napster still uses RMA files to perform DRM functions.
How to open an RMA file
RMA files are not meant to be opened. Rhapsody automatically uses RMA files to perform DRM functions.
