You can't download more files at the same time but this tool should simplify the process for non-premium users:

Hi Ricknroll.
Can you explain more about the use of this tool.
My problem is having some difficulties downloading depositfiles and rapidshare files, as it says "your download link is obsolete" and I often have have to repeat the process for 15 minutes before being able to access to the download.
