    Response.AppendHeader("Content-Disposition", "attachment;" +  Name);
    Response.WriteFile(FileBankPath);
    Response.End();

You should send force-download headers along with the file. I don’t know how you would do that in ASP but basically you have to read the file with some ASP built-in function then output it to the browser attaching

Content-Type: application/force-download;
Content-Disposition: attachment; filename=\yourfile.txt

Judging by your code:

Response.AppendHeader("Content-Type", "application/force-download;");
Response.AppendHeader("Content-Disposition", "attachment; filename="+ Name);

Cheers!
