How to open .MP files on Windows

To open .MP files on Windows, use a file conversion tool to convert the .mp file to a more modern format like .xls or .xlsx.

Step-by-step instructions

  1. Use a file conversion tool to convert the .mp file to a more modern format like .xls or .xlsx.
  2. Alternatively, use a DOS emulator to run the original Multiplan software if available.

Recommended software

  • Microsoft 365
  • LibreOffice
  • Google Docs (web)

Alternative methods

  • Open .MP in a browser-based viewer if desktop apps fail.
  • Try opening .MP on Windows with a secondary app to rule out app-specific issues.
  • Convert .MP only with trusted tools when direct opening is not possible.

Common issues

File won't open

Modern software doesn't natively support .mp files.

  1. Convert the file to a more common format using a file conversion tool.
  2. Use an emulator to run legacy software that supports .mp files.

Data loss during conversion

Some data may not convert correctly due to format differences.

  1. Verify the converted data against the original file.
  2. Try different conversion tools to find the most accurate one.

Security note

Be cautious when downloading conversion tools, as they may contain malware.
