/*****************************************************************************\
CFtpFolder The stuff that tracks the state of a folder. The cBusy field tracks how many sub-objects have been created (e.g., IEnumIDList) which still contain references to this folder's identity. You cannot change the folder's identity (via IPersistFolder::Initialize) while there are outstanding subobjects. The number of cBusy's never exceeds the number of cRef's, because each subobject that requires the folder identity must retain a reference to the folder itself. That way, the folder won't be Release()d while the identity is still needed.\*****************************************************************************/
