Moved to here.
It seems there is not a board about batch file.
But I have a batch file which is diffcult to understand. I post it here if administrators think it's not the suitable place so you can delete it, sorry for trouble.
The purpose of the batch file is to replace a system file but I really want to know the process when I execute it and if I can do the same actions by manually.
