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.

More Information 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. RMA files are often confused with .RM , .RA , and .RAM files, which are also RealNetworks files. However, those file types are associated with RealPlayer media, not Rhapsody. NOTE: In 2016, RealNetworks rebranded Rhapsody as Napster. It is unknown whether Napster still uses RMA files to perform DRM functions.
