I am not quite sure what you mean since the files are written by
text_oarchive etc, and should be read by corresponding streams such as
text_iarchive. I do not know how to write some type information at the
beginning of the files and use a general iarchive to read it first.

This is what I am doing: try to guess the file type by file extension.
If fails, use try/catch to read the file using different iarchive
objects. I think it would be better to judge the file type by file
header.
