Good old .epub & .mobi

If i placed a link to download a .mobi book or a .pub book, how can I success in this odyssey. Tried almost everything, except the right thing. I am using the True Download Stack from DooBox. Are the downloads only for .doc and .pdf?

Any help will be appreciated, as always.

Try compressing the files into a Zip file in Finder first. Right Click -> Compress

Gracias Joe

I try and think it works ok.
