Use the COPY command.
Basic syntax: COPY [OPTIONS] source destination
That is, you just run COPY 源文件路径 目标路径. It is similar to the cp command on Linux.
But the Windows COPY command can only copy files, not folders.
The common options are /V and /Y: /V verifies that the new file was written correctly, and /Y skips the prompt asking whether to overwrite an existing destination file.
