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 669 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 669 files will hopefully be added soon.

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 669 file format or software that uses files with the 669 suffix, please do get in touch - we would love hearing from you.
