How to open CTA files

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

What is a CTA file?

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