How to open GAU files

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

What is a GAU file?

GAU files are MS Flight Simulator Gauge files, which you can read more about below.

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