Convert MMO to another file type
To convert MMO data files to another format, you need PC SOFT WINDEV or other Database software.
Convert a file to MMO
To convert other file formats to the "Proprietary Application Data" file type, you need software like PC SOFT WINDEV or a similar tool.
About MMO files
The .MMO file extension generally serves two distinctly different, yet equally frustrating, proprietary purposes. Most commonly, it is a Data Memo File used by the PC SOFT WINDEV development environment. In this context, it stores large text, binary, or image objects linked to a HyperFileSQL (HFSQL) database. Alternatively, it is a Memory-Map Overlay File used by Memory-Map GPS software to store waypoints, tracks, and routes. Less frequently, it acts as an expenditure invoice for Memo Office accounting, or a gameplay movie file for the Mesen NES emulator.
The primary disadvantage of the .MMO format is its strictly proprietary nature. WINDEV memo files are useless without the accompanying FIC database file, making external extraction nearly impossible without writing custom database queries. Similarly, Memory-Map locks your GPS data into its closed ecosystem, preventing you from natively opening your routes in modern mobile apps or Google Earth. These formats are not supported by web browsers and often require expensive software licenses to access.
If you need to share your GPS routes, the best target format is GPX or KML. However, converting these files typically requires exporting directly from the original software. Standard online converters inevitably fail to process .MMO files because the data structures are undocumented and closed-source.
Because this file format is difficult to open or convert, often only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format - such as the standard ZIP format used by Mesen - viewing or conversion may still be possible.
Convert.Guru analyzes your MMO file, detects the exact format, and lets you read the text inside.
If you want to convert MMO file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use PC SOFT WINDEV or similar software from the "Proprietary Database & GPS Data" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to MMO, try PC SOFT WINDEV or another comparable tool in the "Proprietary Database & GPS Data" category.
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.
