Answers:

Please check that the name of the all the folders that you have created does not contain any space. If that is the case, then remove the space(for eg. 'My Folder' to 'Myfolder') and it should work.
I can see that there is a folder named 'New Folder' which contains a space. Try removing  that and see if that works.

So, Error says that you have some unwanted file/folder in your system which has space in the file name.
Delete that folder and run the command again.
