HI,

I am directory listing and in that listing I have certain files and sub  
directories, now when I click on the files it should download that  
particular file but I am not able to accomplish it, and I have got to  
use send\_file() method.

In the send file Code shown below I have made use of the address of one  
of the files directly so when I click the link of any file it downloads  
it.

THE CODE  
…

def listing

```
          if (params[:dir] !=nil)
               @path = params[:path]+"/"+params[:dir]
          else
               @path ="D:/hr"
          end

               @f=File.ftype(@path)
                          if @f=="file"
                                redirect_to

```

:action=\>‘download\_files’  
else  
@dirEntries = Dir.entries(@path)  
@dirEntries.reject! { |filename|  
filename.starts\_with? ‘.’ }  
end  
end

```
      def download_files

                                send_file('D:/hr/xyz.doc',
                                             :filename =>

```

params[:filename] ,  
:type =\>  
‘application/octet-stream’,  
:disposition =\>  
‘attachment’,  
:streaming =\>  
‘true’,  
:buffer\_size =\>  
‘4096’)  
end
