What is a MW file?
A .MW file is primarily a Maple Worksheet document created by Maplesoft for their Maple software. These files use an XML structure to store mathematical expressions, 2D and 3D graphs, executable code, and standard text.
However, the .MW extension has multiple meanings. It can also act as a label design file used by Brady Workstation, or as a legacy text document from Apple's MacWrite software. Additionally, the MegaWare ransomware family renames encrypted 7-Zip archives with the .MW extension.
How to open MW files?
Because .MW has multiple possible meanings, we recommend using viewer.online/mw to identify the actual format of your file. viewer.online/mw analyzes .MW files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
If you already know the origin of the file, you can open math documents directly with Maple and label design files with Brady Workstation.
Best practices and troubleshooting
If you cannot open your file and its name unexpectedly changed to include the .MW extension, do not try to execute or open it with standard software. Run a reliable antivirus program to check your system for MegaWare ransomware.
If you need to share a Maple Worksheet with users who do not have the software installed, we recommend file conversion to sensible target formats on convert.guru. You can easily convert standard .MW math files to .PDF, .HTML, or .TEX formats.
Summary
Determining the correct software for an unknown file can be confusing. viewer.online/mw directly opens and previews .MW files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
