.ID File Extension

A .ID file is a Lotus Notes User ID File, created by IBM.

Open with IBM Lotus Notes. Available for Windows.

What is a .ID file?

An .ID file is a special type of file used by Lotus Notes and Domino Server, which are programs for managing emails, calendars, and other personal information in a business environment. This file is very important because it contains all the details that identify a user on these systems. When a person is set up to use Lotus Notes, the person in charge, known as the Domino administrator, creates this .ID file. Inside it, you'll find the user's full name, a special number for using Lotus Notes, a security certificate, two keys (one public and one private), and a password.

To open or use this .ID file, you would typically need the IBM Lotus Notes program or the IBM Domino server software. However, it's important to note that these programs are no longer being made, which means they might not be available or supported in the future.

User IDs, like the one in your .ID file, are necessary for logging into IBM Lotus Notes and might also be needed to get into a Domino server. These IDs usually have to be updated or renewed every year because they expire.

If you're using Lotus Notes and want to see the information in your .ID file, you can do so by going to the "File" menu, then to "Security," and finally to "User Security." Given that .ID files hold very personal and sensitive information, it's crucial to keep them in a secure place and make sure they're protected.

If you ever lose your .ID file or forget the password, there might be a way to get it back, but only if the administrator set up a way to recover it beforehand. You can check if this is possible by looking for a "Mail Recovery ID" option in the "Security Basics" section of the "User Security" dialog box in Lotus Notes. If you don't see this option, it means the administrator didn't set up recovery for your .ID, and unfortunately, you won't be able to recover your .ID file in that case.
