About MMO files
The .MMO extension represents three distinct proprietary formats, each requiring specific software to access.
1. WINDEV HFSQL Memo File (Primary Use)
Most commonly, an .MMO file is a "Memo" container used by WINDEV and WEBDEV applications. It operates as a sidecar to a FIC (Data) and NDX (Index) file within an HFSQL database.
- The Problem: You cannot open this file alone. It contains variable-length binary data, rich text, or images that are indexed by the main database file. Without the corresponding FIC file and the original software, the data is unreadable.
- The Solution: To convert the data, you must use the original WINDEV application or the WDMAP tool to export the database tables to CSV, Excel, or XML.
2. Memory-Map Overlay File (GPS Users)
Outdoor enthusiasts encounter .MMO files as proprietary overlays created by Memory-Map.
- The Problem: These files store routes, tracks, and waypoints in a format locked to the Memory-Map ecosystem. They are not natively supported by Google Earth, Garmin devices, or Strava.
- The Solution: Use Memory-Map (v6 or later) to export the data as a GPX file for universal compatibility. Third-party tools like GPSBabel can also convert .MMO to KML or TCX.
3. Mesen Gameplay Movie (Gamers)
Users of the Mesen emulator see .MMO files as gameplay recordings.
- The Problem: This is not a video file. It is a ZIP archive containing a log of controller inputs. It cannot be played in VLC or uploaded to YouTube.
- The Solution: You must load the file in Mesen alongside the original game ROM and use the internal "Export to AVI" feature to create a shareable video.
Convert.Guru analyzes your MMO file, detects the exact format, and lets you read the text inside.
Users also converted NDX, MMOR, FIC, MP3, MP4, MOV, PDF, WDD, TST and ASO files.
The MMO 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 MMO converter.
