如何才能实现文件的转发?就像邮件的收件箱，可以转发邮件,转发的只是副本。
各位帮帮忙，谢谢 啦！！！

我有二个表：receivefile 和 sendfile
转发的代码如下：
<table>
<tr>
<td width="114" height="28" align=center background="../img/img/filebg.gif"><font color="#ffffff">呈报人</font></td>
<td width="120" align=center background="../img/img/filebg.gif"><font color="#ffffff">呈报人部门</font></td>
<td width="118" align=center background="../img/img/filebg.gif"><font color="#ffffff">部门主管签字</font></td>
<td width="70" align=center background="../img/img/filebg.gif"><font color="#ffffff">转发</font></td>
</tr>
<form method="post" action="sendfile.asp" name="form1" >
<%
do while not rs.eof or rs.bof
%>
tr style="border:1px solid" bgcolor="216bb5">
<td height="28" align=center style="border:1px solid">
<a href="showsignfile.asp?id=<%=rs("id")%>"><span class="style2"><%=rs("username")%></span></a></td>
<td align=center style="border:1px solid"><span class="style2"><%=rs("userdept")%></span></td>
<td align=center style="border:1px solid"><span class="style2"><%=rs("receivename1")%></span></td>
<td align=center style="border:1px solid">
<input type="checkbox" name="checkid" id="id" value="<%=rs("id")%>">
</td>
</tr>
</table>.
<% if request("checked")<>"" and id=request("id") then
set conn=opendb("oabusy","conn","accessdsn")
set rs1=server.createobject("adodb.recordset")
sql="insert into resignfile(username,userdept,receivename) select(username,userdept,receivename) from signfile where resenduser="&sqlstr(oabusyname)
rs1.open sql,conn,1,3
end if
%>
<table align="center">
<tr>
<td>
<select name="resenduser">
<option selected>请选择转发人</option>
<% set conn=opendb("oabusy","conn","accessdsn")
set rsname=server.createobject("adodb.recordset")
sql="select distinct name from userinf"
rsname.open sql,conn,1,1
do while not rsname.eof and not rsname.bof %>
<option><%=rsname("name")%></option>
<% rsname.movenext
loop %>
</select>
<input type="submit" name="editsignfile" value="转发" style="border:1px solid ">
</td>
</tr>
</table>
