This suggests to me that your view of what the serialization library is is way of of sync of what it is intended to be and what its intended to be used for. The serialization library saves and restores the state of data in your application. An archive is a data stream where the data is stored. The archive is not manipulated explicitly by the program. There is no place in the library where one could introduce the concept and corresponding code to "remove data from the archive". The only way to do this is to remove the data from the C++ data structures that the archive would correspond to and create another archive. I don't know if that helps, but I think its the best I can do. Robert Ramey Przemyslaw Wojnowski wrote:

It helps a lot. But now I have another question. Could archive interface be changed/extended to support removing from an archive, so interface realization will be able to save/load/remove data selectively? If not, why?
