China DOS Union

Use file merging
copy 1+2+3 4

Question: then if my 1.BAT;2.BAT;3.BAT are combined into one 4.BAT, how can I split it back into the original three BAT files with different contents?

Hehe, the poster above can try it yourself, don't ask others about everything. Sometimes trying it yourself is good too.
Create a few unrelated BAT files yourself and try it out ：）

Haven't I tried enough? I did try it, and afterward in 4.bat there were 3 bat files, and it doesn't recognize English. I just can't understand much of the hlp;
Friend, if a question post is made, help if you can; if you can't, then just pass by, okay?

Not easy to solve!

Ah, never mind, it's nothing important anyway; just learning a bit more

Use the ";" sign

I'm new here. There's a method you can try: first enter the folder you want to copy from, and maybe there are subfolders under it too, that's okay. Use dir/b/s>>list.txt to export the file list first, then use the for command:
for /f %a in (list.txt) do copy %a d:\temp\
But this command also has a drawback: if there are still subdirectories under the original directory, it can't copy the directories, only the files inside them. Hope an expert can improve it!

Another way is, after starting DOS, load Chinese character support. For example, Tianhui, then load the input method Wb(x).com or Py.com, and you can directly enter that New Folder. Method: start DOS, type Tw (this starts the Tianhui Chinese character support system), then type Wb(x).com, this is the DOS version of the Wubi input method, or you can type Py.com, which is the Pinyin input method. You can use Dir to see the name shown for "New Folder" (usually "新建文~1". You can use CD (after typing CD, press the key combination Alt + F2 to enter the Wubi input method, or press Alt + F4 to enter the Pinyin input method) 新建文~1, that is, CD 新建文~1
, then use Copy . e:\ and that will do.

Learned quite a lot again!
