What is an RZX file?

RZX files mostly belong to Fuse. RZX files are recordings used by ZX Spectrum emulators.
These files capture the internal state and input events of a ZX Spectrum session. They do not store a traditional video but rather the sequence of commands needed to recreate the session.

Emulator session: The file records how the system and game behaved during play.
Efficient storage: The data is kept in a compressed form to reduce file size.
Playback requirement: A compatible emulator such as Fuse or Spectaculator is needed to replay the recording.
