Recently, the system crashed, and I could only enter DOS to back up some files. I used the command `copy c:\asd d:\a`. Here, `asd` is a folder, but after reinstalling the system, I found that `d:\a` on the D drive is just an unregistered file, not a folder anymore. What should I do?

The COPY command can only copy files, it seems it can't copy subdirectories. You should use XCOPY or XXCOPY... and so on.

The reason is that there was no a folder in your original D drive, so the copy command merged all the files in the c:\asd directory into one a file. The correct way to copy is like this: md d:\a copy c:\asd d:\a Of course, you don't need to create the target directory first if you use xcopy with the /i parameter. xcopy /i c:\asd d:\a

Oh, is that so? Then does that mean the data I backed up can't be recovered?

It should be using md d:\a xcopy c:\asd /s d:\a In this way, all non-empty subdirectories under the asd folder are all copied over

I think /i is better. No matter whether the directory exists or not, it always copies your files with subdirectories as a directory.
