Extract text from ProtoTRAK CNC programs (PT4)
To convert PT4 CNC programs to another format, you need ProtoTRAK or other Data software.
To convert other file formats to the "Machine Control File" file type, you need software like ProtoTRAK or a similar tool.
The .PT4 file extension is primarily associated with CNC machine program files created for Southwestern Industries ProtoTRAK control systems. These files store specific conversational machining instructions, tool paths, and parameters required to manufacture metal parts. A secondary, less common use is for power consumption data log files generated by the Qualcomm Power Tool, which tracks detailed energy usage metrics during hardware development and testing.
Both applications of the .PT4 format are highly proprietary and heavily specialized. The ProtoTRAK .PT4 format is designed exclusively for specific CNC hardware controllers. This means the files cannot be opened natively by standard desktop operating systems, web browsers, or standard CAD software. The Qualcomm power logs are similarly locked to specific diagnostic software ecosystems. This creates a significant problem: sharing or reviewing the data is nearly impossible if the recipient does not have the exact machine controller or an expensive license for the proprietary software.
Users typically need to convert .PT4 files to standard, accessible formats like TXT, CSV, or standard G-code (GCODE) for easier review, documentation, or cross-compatibility with generic CAM software. However, because these files use closed, undocumented data structures, standard online converters consistently fail to process them. Often, only the original hardware or specialized offline software can properly read or export the structured data.
Despite these strict limitations, just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. We can inspect the file and show underlying text or internal hex content, which might help you recover the raw routing coordinates or CSV telemetry data.
Convert.Guru analyzes your PT4 file, detects the exact format, and lets you read the text inside.
Users also converted S19, RPG, SAS and PT3 files.
If you want to convert PT4 file to , you can use ProtoTRAK or similar software from the "CNC Machine Program Storage" category. In the File menu, look for Save As… or Export….
To convert files to PT4, try ProtoTRAK or another comparable tool in the "CNC Machine Program 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 PT4 converter.
