How to open FZ4 files

Did your computer fail to open a FZ4 file? We explain what FZ4 files are and recommend software that we know can open or convert your files.

What is a FZ4 file?

FZ4 files are JB BAHN vehicle (Zoom4) files, which you can read more about below.

The FZ4 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 FZ4 opener may not be able to open all kinds of FZ4 files. In this case, though, we only know of one specific use.
