Opening ID files

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

What is an ID file?

Files that contain the .id file extension are usually 3D graphics files that are used by a variety of software applications. Some of the programs that use ID files include AOL instant messenger (for buddy icons), Pegasus Mail and certain disk identification files.

Files that contain the .id file extension are also used by Lotus Notes. These ID files contain identifying information about a user for a Domino Server. These files may contain the name and password of a user, the license number for the software and the public and private software keys. These ID files are usually created by system administrators.
