How to open CPJ files

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

What is a CPJ file?

CPJ files are WinOnCD Project files, which you can read more about below.

The CPJ 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 CPJ opener may not be able to open all kinds of CPJ files. In this case, though, we only know of one specific use.

WinOnCD Project

Through our analysis of CPJ files, we know that one use of the format is WinOnCD Project. 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!

These apps are known to open certain types of CPJ files. Remember, different programs may use CPJ files for different purposes, so you may need to try out a few of them to be able to open your specific file.
