How to open CH_ files

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

What is a CH_ file?

The CH_ file extension indicates to your device which app can open the file. However, different programs may use the CH_ file type for different types of data.

While we do not yet describe the CH_ file format and its common uses, we do know which programs are known to open these files, as we receive dozens of suggestions from users like yourself every day about specific file types and which programs they use to open them.

We are continually working on adding more file type descriptions to the site, so if you have information about CH_ files that you think will help others, please use the Update Info link below to submit it to us - we'd love to hear from you!
