source Required. Specifies the location and names of the files you want to copy. This parameter must include either a drive or a path./指定要复制的文件。
destination Specifies the destination of the files you want to copy. This parameter can include a drive letter and colon, a directory name, a file name, or a combination of these./指定新文件的位置和/或名称。
/A Copies only Source files that have their archive file attributes set. /a does not modify the archive file attribute of the source file./仅复制有存档属性集的文件，但不更改属性。
/M Copies Source files that have their archive file attributes set. Unlike /a, /m turns off archive file attributes in the files that are specified in the source./仅复制有存档属性集的文件，并关闭存档属性。
/D:m-d-y Copies source files changed on or after the specified date only. If you do not include a MM-DD-YYYY value, xcopy copies all Source files that are newer than existing Destination files. This command-line option allows you to update files that have changed./复制在指定日期或指定日期以后更改的文件。如果没有提供日期，只复制那些源时间比目标时间新的文件。
/EXCLUDE:file1[+file2][+file3]... Specifies a list of files. At least one file must be specified. Each file will contain search strings with each string on a separate line in the file.When any of the strings match any part of the absolute path of the file to be copied, that file will be excuded from being copied. For example, specifying the string obj will exclude all files underneath the directory obj or all files with the .obj extension./指定含有字符串的文件列表。每个字符串在文件中应位于单独的一行。如果任何字符串与复制文件的绝对路径的任何部分相符，则排除复制该文件。例如，指定如 \obj\ 或 .obj 的字符串会分别排除目录 obj 下面的所有文件或带有.obj 扩展名的所有文件。
/P Prompts you to confirm whether you want to create each destination file./创建每个目标文件之前提示你。
/S Copies directories and subdirectories, unless they are empty. If you omit /s, xcopy works within a single directory./复制目录和子目录，不包括空目录。

/W Displays the following message and waits for your response before starting to copy files:Press any key to begin copying file(s)/提示你在复制前按键。
/C Ignores errors./即使有错误，也继续复制。
/I If Source is a directory or contains wildcards and Destination does not exist, xcopy assumes Destination specifies a directory name and creates a new directory. Then, xcopy copies all specified files into the new directory. By default, xcopy prompts you to specify whether Destination is a file or a directory./如果目标不存在，且要复制多个文件，则假定目标必须是目录。
/Q Suppresses the display of xcopy messages./复制时不显示文件名。
/F Displays source and destination file names while copying./复制时显示完整的源文件名和目标文件名。
/L Displays a list of files that are to be copied./显示要复制的文件。
