Hello,

You can use ASHX file (say, downloadfile.ashx) and use the following code (not tested, but it will be something like that) in it:

C#

Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=abc.txt");
Response.WriteFile(Server.MapPath("\\servername\folder1\folder2\folder3\abc.txt"));
Response.End();

and then use this in your anchor tag like:

HTML

<a href="downloadfile.ashx"  target=""_blank"">Click me</a>

Note: You can also pass parameters for downloading different files like:

HTML

<a href="downloadfile.ashx?file=abc.txt"  target=""_blank"">Click me</a>

and then, in ashx file, use the file name to download the appropriate file.

Then, replace your following code

Response.Write("<br>" + file);

by something like this

Response.Write("<br><a href="downloadfile.ashx?file=" + file + "">" + file + "</a>");</pre>

You'll maybe need to change your filepath from absolute to relative.

Hope it helps ;)
