About JMD files
The .JMD file extension typically represents one of two proprietary formats: a Raycity game data file created by J2M Soft or a local media library database utilized by JRiver Media Center. In Raycity, a discontinued racing MMO, these files act as closed archives holding 3D models, textures, and game engine configurations. In the JRiver ecosystem, .JMD files store granular metadata, playlists, and exact file paths for massive local audio and video collections.
Users usually want to convert these files to escape platform lock-in. Gamers attempt to extract 3D assets into universal OBJ or PNG formats for modding. Media enthusiasts often need to convert their JRiver library data into standard XML or CSV files to migrate to other server software like Plex or Jellyfin. The primary disadvantage of the .JMD format is its proprietary, closed-source nature. It requires a paid software license to access in the case of JRiver, and it completely locks your metadata inside a single ecosystem. It is not supported by web browsers, universal database viewers, or standard text editors.
Because this file format is difficult to open or convert, standard online converters universally fail. They lack the specific parsing algorithms required to read undocumented game engine archives or JRiver's proprietary database schema. Often, only the original software can properly read or export the data. We can inspect the file on a binary level and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your JMD file, detects the exact format, and lets you read the text inside.
If you want to convert JMD file to EC, TTD, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF or DAT, you can use JRiver Media Center or similar software from the "Game Data and Database Storage" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to JMD, try JRiver Media Center or another comparable tool in the "Game Data and Database Storage" category.
The JMD 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 JMD converter.
