XCOPY.EXE was created in a way that it must be assigned an input handle in order to work. Use the echo command and a vertical bar character to create the needed handle.
Example 1 - pipe nothing to xcopy
DOS echo | xcopy w:\OldDir w:\NewDir\ /s
The echo command can also be used to pipe the correct answer to a question -
Example 2 - pipe a "d" character to the question "Does W:\newdir specify a file name or directory name on the target (F = file, D = directory)?"
(This question is not asked if the directory already exists or if there is a backslash after "w:\NewDir" like in example 1.)
