I believe you cannot download folders using the ReadyCLOUD website. This is most likely due to the fact that this service is browser based and browsers are not capable of downloading folders. However, you can select all files within a folder at once and download them.
If you use the ReadyCLOUD Desktop App you can easily access a share by clicking on it. This will open the Windows Explorer (assuming you are using Windows). From there you can copy folders as you would normally do.
