How to open C3 files

Did your computer fail to open a C3 file? We explain what C3 files are and recommend software that we know can open or convert your files.

What is a C3 file?

C3 files are 3D model files, which you can read more about below.

The C3 file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a C3 opener may not be able to open all kinds of C3 files. In this case, though, we only know of one specific use.

Through our analysis of C3 files, we know that one use of the format is 3D model. We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats. We'd love hearing from you if you have information about the format.

We have not verified any programs yet that works with this specific format. If you know any, please use the 'Suggest a program' link below. Thanks!
