Software, that you can use to convert
How to convert the file from AZW3 to APNX?
To successfully convert the AZW3 file to APNX, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.AZW3).

What is a file conversion?
A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. AZW3 to APNX. To obtain a matched structure of the data, it is necessary to use an appropriate converter.
Program for converting AZW3 files to APNX files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension APNX, while before this step we had the AZW3 file). For the programs, the difference is on a much higher level – either the application will be able to open a new APNX file, or not.
