In DOS, I usually use two methods to open files:
1. Directly input the file path and name. For example, "c:\windows\config.exe" (For executable files, you don't need to input the suffix, but be very careful. If not done properly, it may execute other programs, such as com. To prevent misoperation or opening viruses, it's best to bring the complete path and suffix).
2. start, which is a way very liked in batch processing. The advantage is that when opening a file or running an executable program, you don't need to wait for them to close before exiting. The usage is the same as the first method; you just need to add "start " in front.
When the path has spaces, you must enclose the entire path with double quotes. For safety, it's recommended to enclose all paths with quotes.
