In new version, i think in EHP5 onwards we have new element called ACFUPDOWN element, using that we can upload multiple files at a time.
There is an Element called ACFUpDownload which has been available since NetWeaver 7.01 (ERP 6.0 Enhancement Package 4 - not 5 has suggested by this posting). However it is designed to work with the SAP Content Server. It doesn't upload/download the data directly to/from the Web Dynpro session. If you search here on SCN, I have a tutorial and sample code on how to ACFUpDownload and how to adapt it to use in direct Web Dynpro situations (basically a custom handler class).
You might also consider using ZIP files. That way you have only one file to upload or download, but it contains many inner files. You can process ZIP files on ABAP using CL_ABAP_ZIP.
