What is the maximum length of a Window's command-line (cmd.exe) command?
提问by Jesse Webb
There are many people asking questionson SO about how to get around the cmd.exe command maximum length. I was wondering what actually is the Windows command-line length limit? Is it different between version of Windows? Does using a 32-bit vs. a 64-bit version affect this limitation?
