Extract text from Mastercam V7 part files (MC7)
To convert MC7 part files to another format, you need Mastercam or other Cad software.
To convert other file formats to the "Legacy CAM Part / PLC Bytecode" file type, you need software like Mastercam or a similar tool.
The .mc7 extension represents two distinct, highly technical file formats used in industrial engineering. The most common use (approx. 59%) is as a Mastercam Version 7 Part file. Released in the late 1990s by CNC Software, these files contain 2D/3D geometry, toolpaths, and machining operations used to program CNC machines. Because Mastercam V7 is a legacy format that predates the modern .mcam and mcx standards, these files are effectively "locked" in time. They are binary and proprietary, meaning you cannot open them in standard CAD viewers, web browsers, or generic converters. To access the geometry, you typically must use a newer version of Mastercam to "update" and open the file, or ask the original creator to export it to a neutral exchange format like STEP or IGES.
The second common use (approx. 18%) is as a SIMATIC S7 Program Block for Siemens PLCs (Programmable Logic Controllers). In this context, the .mc7 file contains compiled machine code (bytecode) that runs directly on S7-300 or S7-400 series controllers. These are not "documents" but executable logic blocks generated by STEP 7 software. You cannot convert these to PDF or image formats; they are strictly for industrial automation environments and require the Siemens TIA Portal or SIMATIC Manager for editing or decompiling.
Convert.Guru analyzes your MC7 file, detects the exact format, and lets you read the text inside.
Users also converted MC8, MCX and MC9 files.
If you want to convert MC7 file to , you can use Mastercam or similar software from the "Legacy CNC Part Storage" category. In the File menu, look for Save As… or Export….
To convert files to MC7, try Mastercam or another comparable tool in the "Legacy CNC Part Storage" 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 MC7 converter.
