Opening ID2 files

Did your computer fail to open an ID2 file? We explain what ID2 files are and recommend software that we know can open or convert your ID2 files.

What is an ID2 file?

Files that contain the .id2 file extension are most commonly used by the Microsoft Live Messenger instant messenger application. The ID2 files that are used by the software allow the application to store image data for the Microsoft Live Messenger program.

Some of the data that is contained in the ID2 files include the user's signature data, emoticon details, keyboard shortcuts and avatar settings. A user's ID2 files are encrypted. The user's Microsoft Passport ID is used to decrypt the files so that they can be used in the Windows Live Messenger program when a user begins a Windows Live Messenger session.

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.
