Hi Robert,
You can upload multiple n3, rdf, ttl and other RDF data files via the WebDAV
rdf_sink folders as detailed at:
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtuosoRDFSinkFolder
Are these the instructions you have been following as I have just tested
myself on Mac OS X mounting my Virtuoso WebDAV folder in the Finder and copying
RDF data files into it ?
Also, what version virtuoso (virtuoso-t - ?) are you running and what is the
WebDAV client you are using to copy files in with ?
Best Regards
Hugh Williams
