Notes about the CKI file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The CKI file type is primarily associated with 'Off by One Browser' by Off By One Productions, a division of Home Page Software Inc.. Persistent HTTP cookies are stored across sessions in the file HPSW.CKI, which may be safely deleted between sessions for maximum privacy.
