What is a HMX file?

HMX files are Help & Manual Project files, which you can read more about below.

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