Opening ST9 files
Did your computer fail to open a ST9 file? We explain what ST9 files are and recommend software that we know can open or convert your ST9 files.
What is a ST9 file?
While we do not yet have a description of the ST9 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 ST9 files will hopefully be added soon.
