How to open MSA files

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

What is a MSA file?

MSA files are Atari MSA Disk Image files, which you can read more about below.

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