Game replay created by LOLReplay, a game replay recorder and manager for League of Legends (LoL); used for re-watching gameplay and sharing the replay with others online; can only be opened by LOLReplay (not by the League of Legends game), but still requires that League of Legends be installed on the computer.

LRF files are not video files and cannot be opened by video playback programs. Instead, they can only be played with the LOLReplay software. This is because LRF files capture events that take place during gameplay, and the software re-simulates the events when it is replayed. This allows the file sizes to stay small in comparison to a full motion video equivalent. It also allows the observer to move over the map, select units, and view the replay from multiple perspectives. NOTE: LOLReplay is discontinued and no longer available for download.
