Opening GCO files

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

What is a GCO file?

Every day thousands of users submit information to us about which programs they use to open specific types of files.

While we do not yet have a description of the GCO file format and what it is normally used for, we do know which programs are known to open these files. See the list of programs recommended by our users below.

We are constantly working on adding more file type descriptions to the site - the current count exceeds thousand by far, and more information about GCO files will hopefully be added soon.

Try a universal file viewer

Try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and most likely yours too. Download Free File Viewer here.

About File Extension GCO

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.

If you have additional information about the GCO file format or software that uses files with the GCO suffix, please do get in touch - we would love hearing from you.
