Hi MayurNarsale,
It is the attachment table, if you do not need the attachment table, please use control "CuteWebUI:Uploade", it has the same functions as the "CuteWebUI:UploadAttachments", but will not build the attachment table.
<CuteWebUI:Uploader ID="uploader1" runat="server" MultipleFilesUpload="true">
</CuteWebUI:Uploader>
Regards,
Ken
