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
