What is an NMW file?

NMW files mostly belong to Microsoft NetMeeting. NMW files are created by Microsoft NetMeeting for whiteboard sessions. They record session data when participants draw or add notes on the shared whiteboard during a remote meeting.
This file stores visual annotations and markings in a proprietary format that was used to improve remote collaboration.
Key details summarized by FilExt.com include:
  • Purpose: Captures whiteboard drawings and notes during meetings.
  • Usage: Facilitates real-time annotation in NetMeeting sessions.
  • Format: Proprietary, meaning modern software might not support it directly.
  • FilExt.com note: If you have an NMW file, opening it typically requires using Microsoft NetMeeting or a legacy viewer that can handle this format. Backup the file before trying any conversion.

    How can I open an NMW file?

    You need a suitable software like Microsoft NetMeeting to open an NMW file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your NMW file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NMW file directly in the browser:. Just drag the file onto this browser window and drop it.
