The easy way is to put your uploaded files into a directory in
/priv/static then any requests to
http://yoursite.com/static/some/path/your_new_file.bin

Otherwise, if your files are small, you could just have a controller
return {output, FileContents, Headers}, where FileContents could be
the result of file:read_file/1
(http://erldocs.com/17.0/kernel/file.html?i=0&search=file:read_file#read_file/1)

Ooootherwise, if your files are large, you can write a generator
function and return a streaming with with {stream, GeneratorFun, Acc}
(see http://chicagoboss.org/api-controller.html)

Hope that helps,

-Jesse
