Question

Can anybody tell me how to do the following in in a Windows batch script? (*.bat):

• Create a folder only if it doesn\'t already exist

Answer 1

mkdir C:\VTS 2> NUL

create a folder called VTS and output A subdirectory or file TEST already exists to NUL.

or

(C:&(mkdir "C:\VTS" 2> NUL))&

change the drive letter to C:, mkdir, output error to NUL and run the next command.
