How to Compress ISO to CSO with Smaller Size Correctly on PC and Android

In a previous article, I wrote an article about how to compress ISO to CSO correctly and easily, but I forgot and remembered when I revised the article.


This article describes how to compress ISO to CSO or change ISO format to CSO. Compressing or converting ISO to CSO is not the same as renaming the file format to CSO and using an application someone else made.
