# Unreadable Codes In MAS AIO (Applies to MAS AIO 1.6) ------------------------------------------------------------------------ MAS requires some of Microsoft's official files in order to perform activation. In order to make an all-in-one version, it's required that we need to include those files in our AIO .cmd file somehow. To do that, MAS uses AveYo's [Compressed2TXT](https://github.com/AveYo/Compressed2TXT). It can convert files to text format and Vice-Versa. However, if you are not feeling comfortable using it then you can use MAS separate files version. ------------------------------------------------------------------------ **1st block** of compressed2TXT code contains the below file.
