Opening MSN files

Did your computer fail to open a MSN file? We explain what MSN files are and recommend software that we know can open or convert your MSN files.

What is a MSN file?

Files that contain the .msn file extension are most commonly used by the Microsoft Windows operating system. The MSN files that are used by the Windows OS contain a list of blocked Internet IP addresses which prevent a user from accessing certain Internet locations and websites.

The .msn file extension is also used for installer files for the MSN Content Plus MSN Messenger enhancement tools. These allow users to enhance the features of their MSN instant messenger application.

The Descent computer game also uses the .msn file suffix. These MSN files contain the mission files that are referenced by the game during a user’s play.

Software that will open, convert or fix MSN files

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
