Hi,
the DB provider and the DownFile.aspx is open source.
You can change the code so that you can provide a new url pattern as you like.
for example, in the SqlFileStorage.cs , modify the public override string GetFileUrl(string filepath)
And you can add mime header when the DownFile.aspx is executed.
for example, in the DownFile.aspx.cs , add Response.ContentType="application/msword"; when the file is *.doc
