What is a MWP file?
The core fact is that an .MWP file usually stores a Programmable Logic Controller (PLC) project. The most common software that creates these files is Siemens Micro/WIN. Some files might also be a Mitsubishi PLC program file.
However, the .MWP extension has another older use. It can be a Lotus Word Pro SmartMaster File or a standard word processor document created by IBM. Because an .MWP file has multiple possible meanings, it is important to identify your specific file type.
How to open MWP files?
If your file is a PLC project, you need the specific engineering software. Siemens Micro/WIN is the main program to open and edit Siemens PLC files. If the file is an old word processor document, you need IBM Lotus Word Pro.
viewer.online/mwp can analyze .MWP files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Best practices and troubleshooting
If you cannot open the file, do not force it to open in a standard text editor. This might corrupt the binary data. If you are unsure what the file is, use a secure online tool. We recommend viewer.online/mwp to identify the actual format of the user's file.
