Bug 86011 [Wizards] Need to support creating multiple folders at once
It is currently not possible to create more than one folder at a time using the New folder wizard like it is with the import dialogs for instance. We would need to change ResourceAndContainerGroup so that it accepted paths in validateResourceName() and WizardNewFolderPage to build these.

/**
     * Sets the value of this page's container name field, or stores
     * it for future use if this page's controls do not exist yet.
     *
     * @param path the full path to the container
     */
    public void setContainerFullPath(IPath path) {
        if (resourceGroup == null)
            initialContainerFullPath = path;
        else
            resourceGroup.setContainerFullPath(path);
    }
    /**
     * Sets the value of this page's file name field, or stores
     * it for future use if this page's controls do not exist yet.
     *
     * @param value new file name
     */
    public void setFileName(String value) {
        if (resourceGroup == null)
            initialFileName = value;
        else
            resourceGroup.setResource(value);
    }
    /**
     * Checks whether the linked resource target is valid.
     * Sets the error message accordingly and returns the status.
     *  
     * @return IStatus validation result from the CreateLinkedResourceGroup
