China DOS Union

For example, I have an a01 folder under drive D:, with 01.txt and a 02 subfolder. I want to copy it to the temp directory under drive D: so that it results in d:\temp\a01 along with the subfolders and files inside.

I used the commands xcopy d:\a01 d:\temp /e and xcopy d:\a01 d:\temp /s, but only 01.txt and the 02 folder are copied, and the main folder a01 isn't copied.

Please ask how to copy along with the a01 folder?

By the way, I entered cmd by clicking [Start][Run] under the XP system. Is xcopy only usable in pure DOS?

There is someone who answered online, and the answer is as follows:

xcopy cannot directly achieve the function you want because it only recognizes the things under the specified directory and does not recognize the folder itself:
It must be like this, adding the name of the target folder.
xcopy d:\a01 d:\temp\a01 /e /s /i
