Notes about the CID 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 CID file type is primarily associated with 'CallerID' by AnalogX. CallerID is a program that uses any Unimodem/V-compatible voice modem that has Caller ID support to track incoming calls; including who is calling and their number (if available), how many calls have been received from this person, when the first call and when the last calls were logged, and more.
