Opening CATOM files

What is a CATOM 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 CATOM 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 CATOM files will hopefully be added soon.
