如何破解免安装DVD版游戏的压缩文件？

I am looking for how to remove the installation of DVD games without installing them. I start with the first RAR and automatically read the subsequent RAR files, right-click on it and save it in a folder. Then you can install it. If it is an installation-free game, simply find the EXE file in the folder where the game is stored and run it to play. I also found that some websites or folders often have instructions about how to run the game and its precautions when downloading from the internet.
