Accessing external file system files

I am getting files uploaded and into a directory inside RAILS_ROOT called docstore. I want to provide a Download link to http://localhost:3000/docstore/7/some_file.ext

The message I get is Recognition failed for "/docstore/7/Accounting_Entries.xls"

Is this a routing issue? Routing is an area I have never really got the hang of. How do I overcome this? All I want is that when the user clicks on the Download link, he should be able to download the xls or whatever document is being pointed to.

Thanks Nelson... I went through the link and I dont see any probs making it work. For sake of completion, I'll post actual results in here tomorrow.
