Opening MCO files

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

What is a MCO file?

Files with the .mco extension are used by the Windows Live Messenger instant messaging application. Windows Live Messenger allows users to communicate in real-time via online instant messaging technology. The MCO files used by this software contain flash-based animations that are similar to emoticons, but are animated and much larger in size. These files are commonly referred to as Winks.

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.
