How to open 4Q files
Did your computer fail to open a 4Q file? We explain what 4Q files are and recommend software that we know can open or convert your files.
What is a 4Q file?
4Q files are Quartet ST module files, which you can read more about below.
The 4Q file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a 4Q opener may not be able to open all kinds of 4Q files. In this case, though, we only know of one specific use.

We have not yet described in detail what these files contain and what they are used for, but our team is working tiredlessly through thousands of file formats. We'd love hearing from you if you have information about the format.
