Permissions on subfolders

The new version supports permissions and qouta's on subfolders. I would like a directory structure like this:
RootFolder
    UploadFolder
    DownloadFolder

How do I set the permissions on the sub folders so that one on shows the upload arrow and the other only shows the download arrow.
I also need different qoutas.
Thanks.

You should use AddSubfolder method of FileVistaRootFolder class for this purpose.

For instance, you can set Upload permissions, 1000 KB quota and allow *.jpg files on subfolder "UploadFolder" like this:
 
rootFolder.AddSubfolder("UploadFolder", FileVistaPermissions.Upload, false, 1000, FileVistaQuotaUnit.KB, "*.jpg");

You can also set the access control for subfolders at any depth. Here is an example for setting ReadOnly permissions, unlimited quota and allow any files on subfolder "SubFolder1/SubFolder2". 

rootFolder.AddSubfolder("SubFolder1/SubFolder2", FileVistaPermissions.ReadOnly, true, 0, FileVistaQuotaUnit.KB, string.Empty);

What is the namespace for the AddSubFolder method of the rootFolder object?

The FileVistaRootFolder class is in the GleamTech.Web.Controls namespace.
