Sorry if I didn't make it clear.
How my project work is,
1.client upload a file, and the administrator downloads the file.
2.administrator will edit the file, and submit to the website(its 1 to 1 service), now
3.the client should see a list of articles(can only see own's submission), and there is a field can download the edited file. I want "Download" instead of the file name, I am currently using "download" extension, but it shows the full file name.
