2. Back up the "chunk0.dat" file in the folder, which will be replaced later.
3. Decompress the downloaded quiet MOD compressed package, and you can see that there are two folders named "Assets" and "QAR Tools".
4. Open the "QAR Tools" folder, and you can see the executable file named "MGSV _ QAR _ Tools. exe".
5. Drag the "chunk0.dat" file in the Steam game installation directory to the top of "MGSV _ QAR _ tool.exe", and the file will be decompressed to get a folder named "chunk0" and a configuration file named "chunk0.inf".
6. Drag the quiet MOD "Resources" folder to the "chunk0" folder to merge and overwrite all files.
7. Finally, drag "chunk0.inf" (note that it is an inf file, not a dat) to "MGSV _ QAR _ tool.exe" and repackage it into a brand-new "chunk0.dat" file. After running the game, you can play quietly.
