Export all refs with tree structure

Can you tell me how to export all references while preserving the folder structure? Is it possible to import my .bsl file into biblioweb?
Thanks.

When you export references, it is not possible to maintain the folder structure. BiblioWeb can post your database on the Web. In the setup panel, you can select another *.bsl file in BiblioWeb. So there is no need to import unless you want to merge two databases.
