Extract text from MCO files
To convert your MCO file to another format, you need Windows_Live_Messenger or other Plugin software.
To convert other file formats to the "Emoticon Archive" file type, you need software like Windows_Live_Messenger or a similar tool.
The .MCO file extension is most notably associated with Windows Live Messenger Winks, a legacy format for animated emoticons and overlays used in the early 2000s. These files are technically compressed archives (often similar to CAB or ZIP) containing SWF (Adobe Flash) animations and XML metadata. Because Microsoft discontinued the service and Adobe ended Flash support, accessing these files today is difficult; users often find them in old backups and cannot view them without extraction. A secondary but significant use of the .MCO extension is in PC gaming, specifically for 3D model assets or collider meshes in simulation games like My Summer Car and Scrap Mechanic. These binary files contain geometry data proprietary to the game engine.
For MSN Winks, the primary goal is typically extraction or conversion for archival purposes. Since the original software is defunct, the most practical workaround is treating the file as an archive to retrieve the internal media. Users should convert the extracted Flash files to modern formats like MP4 or WebP for web compatibility. For Game Assets, direct conversion to standard 3D formats like OBJ or FBX usually requires specific community-made modding tools or hex editing, as generic 3D converters like Blender do not natively support proprietary game colliders.
Convert.Guru analyzes your MCO file, detects the exact format, and lets you read the text inside.
Users also converted CTT, ML20, TSP and CRO files.
If you want to convert MCO file to CRO, TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD or LOCK, you can use Windows_Live_Messenger or similar software from the "Messenger Wink Animation" 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 MCO, try Windows_Live_Messenger or another comparable tool in the "Messenger Wink Animation" category.
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 MCO converter.
