What is the correct way to copy files in Windows Cmd using xcopy?

Question

cmd/bat

The xcopy command copies files but asks the question:

>xcopy build "target/client" /E
Что означает target/client:
имя файла или каталога
(F = файл, D = каталог)? D

How to answer it in advance, on the command line itself?

Answer 1

Previously, I often made mistakes like this - you need to specify the path correctly:
The last backslash says that the target is a folder, not a file.
