What is a U23 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 U23 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 U23 files will hopefully be added soon.
