What is a .MCO file?
The file extension .MCO is associated with a Live Messenger Winks File. This type of file contains Flash-based animations known as Winks. These animations are used in Windows Live Messenger, which was previously called MSN Messenger. Winks are similar to emoticons but are typically much larger and more elaborate animations.
Winks can be sent to other users within the messaging program to express emotions or reactions in a more dynamic way than static emoticons. The .MCO files that contain these Winks can be opened using Microsoft Windows Live Messenger.
To add new Winks to Windows Live Messenger, you might use tools like Messenger Jump! MSN Winks Installer or MSN BackUp. These programs help manage and install Winks into the messenger application.
It's important to note that Windows Live Messenger was discontinued in 2013, and its services have been integrated into Skype. This means that new users cannot use Windows Live Messenger to open .MCO files, and existing users might have migrated to Skype, which does not support the .MCO file format. Therefore, accessing and using .MCO files in the original intended environment is no longer possible through standard means.
