How to open GCA files

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

What is a GCA file?

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

We are continually working on adding more file type descriptions to the site, so if you have information about GCA 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!
