windows - Create folder with batch but only if it doesn't already exist

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

In more detail, I want to create a folder named VTS on the C: drive, but only if that folder doesn't already exist. I don't want to overwrite the contents of the folder if it already exists and the batch is executed.

You just use this: if not exist "C:VTS" mkdir C:VTS it wll create a directory only if the folder does not exist.

Note that this existence test will return true only if VTS exists and is a directory. If it is not there, or is there as a file, the mkdir command will run, and should cause an error. You might want to check for whether VTS exists as a file as well.
