Files with the extension .c are known as "C/C++ Source Code".

This developer format was added to our database by a visitor to this site, but no additional information was provided.

We have yet to investigate the c file extension any further, or there was simply not enough information available at the time to report accurately on the format. If you know how to open c files or even how to convert or edit them, please use the form below.

However, it is possible that other file formats exist which also use the c extension, so please let us know if you do not think the c extension matches the file format you are looking for.
