What is a .CIS file?

A .CIS file is a type of settings file used by a program called CheckInbox, which was designed to run on Windows computers. This program helped users manage their email accounts more efficiently by organizing and updating them with new emails. The .CIS file specifically stores configuration details for the email accounts that a user has added to CheckInbox. This includes information such as the email address, the name of the POP3 server, the username, and the password associated with each email account.

The .CIS files are typically created when a user decides to back up their email account settings using CheckInbox. To make a backup of the settings, users would go to the "Help" menu in the program and choose "Backup Account Settings." If a user needs to open or restore these settings from a .CIS file, they would follow a similar process, going to the "Help" menu and selecting "Restore Account Settings." CheckInbox was known for its simplicity and effectiveness in managing multiple POP3 email accounts, alerting users promptly when new emails arrived. However, it is important to note that CheckInbox has been discontinued by its developer, VicTech Software, which means it is no longer available for new downloads or official support.

To open a .CIS file, you would have needed CheckInbox software from VicTech Software, but since the software is discontinued, opening these files might now be challenging. If you still have CheckInbox installed, you can use it as described above. If not, you might need to look for alternative software that can read .CIS files or try converting them to another format compatible with current email management programs.
