You will see Create Folder dialog when you want to create new directory.
Specify name of the new directory in New folder name box. If you specify only name, new subdirectory with the name will be created in current working directory. You can also specify full path to create new directory anywhere.
When creating remote directory, you may specify also its initial permissions in Attributes box. Setting permissions is not available with WebDAV and S3 protocols.
The Use same settings next time checkbox makes your options become default options for future directories.
