no sms deleted folder?

Question

Hi,

I'm new to Android and trying to convert a Windows Mobile app to java/android.

In WM there are the followning standard folders:

Inbox,Sent, dratfs, outbox, deleted.

I'm able to access all folders except deleted with

Uri.parse("content://sms/XXXXXX")

1) Is deleted folder missing?
2) Is it possible to create user folders, like "content://sms/My Folder"

Thanks, Nicholas
