About RRF files
The .RRF file extension primarily represents two fundamentally different formats: Ragnarok Online Replay Files and UMLS Metathesaurus Rich Release Format data files. In gaming, an .RRF file records in-game sessions from the Ragnarok Online MMORPG. It is not a standard video file; instead, it stores a sequence of game data coordinates and engine instructions. In healthcare and data science, .RRF stands for Rich Release Format. It is used by the U.S. National Library of Medicine to distribute massive sets of healthcare terminology, clinical drug data like RxNorm, and biomedical vocabularies. Both variations of the format are highly specialized and restrictive. Ragnarok replays require the exact client version to playback correctly and cannot be played in standard media players. Meanwhile, UMLS .RRF files are massive pipe-delimited text files. Trying to open a multi-gigabyte RxNorm dataset in standard spreadsheet software will freeze your computer, requiring database tools or custom scripts to query. To share a Ragnarok replay online, you must screen-record the playback to convert it to MP4 or WebM. For the UMLS data files, extracting the raw text into a standard CSV, JSON, or SQL dump is necessary for modern database ingestion.
Convert.Guru analyzes your RRF file, detects the exact format, and lets you read the text inside.

The RRF Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our RRF converter.
