What is a CIS file?

CIS files mostly belong to CheckInbox by VicTech Software. CIS is the file extension for a CheckInbox settings file. CheckInbox is a program that enables a user to organize and stay updated with their email. The program has been developed by VicTech Software and is available for Windows platforms. It allows users to streamline the usage of multiple email accounts. Multiple POP3 email accounts can be added to it, and the program immediately notifies users when they receive an email. A CIS file contains user settings for CheckInbox. It contains details about the email accounts added in the program. These details include the email address, POP3 server name, user name, and password. CheckInbox generates CIS files when a user backs up account settings. Backups can be created by selecting Help and then selecting Backup Account Settings. CIS files can be imported when required. This can be done by selecting Help and then selecting Restore Account Settings. The CIS format may also be associated with TAPCIS (The Access Program for the Compuserve Information Service), which was a software application for MS-DOS that streamlined the process of accessing and managing CompuServe email accounts.
