Knime Batch Problem


I am new in knime development. I want to do a batch process, and I have it but i have this error when I execute it.

main BatchExecutor   Workflow directory is not a directory

This is the batch code: 

cd C:/Program Files/KNIME/
knime.exe -consoleLog -reset -nosplash -noexit
-application org.knime.product.KNIME_BATCH_APPLICATION
-nosave  -workflowDir='C:/Users/DWCONSULWARE/Desktop/EJM/Primera Parte'

Pls help me 

Thanks you

You may need to use double quotes to enclose the path to the workflowDir, or alternatively try using a workflowDir that doesn’t contain a space.
