Opening CID files

Did your computer fail to open a CID file? We explain what CID files are and recommend software that we know can open or convert your CID files.

What is a CID file?

The .cid file extension is used by a variety of software applications. It is most commonly associated with the Navigator astronomy software to store chart image descriptions. The .cid file extension is also used for AnalogX CallerID files and coDiagnostiX user defined implant files.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
