Opening US4 files
Did your computer fail to open an US4 file? We explain what US4 files are and recommend software that we know can open or convert your US4 files.
What is an US4 file?
While we do not yet have a description of the US4 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 US4 files will hopefully be added soon.
