Hi AngieOng,
You can extract the file attachment from the form and map it to a separate document library.
Then, you can create a "mashup" dashboard page that pulls the data from the form library and the document library and shows both.
We have done numerous webinars talking about "dashboards".
To get the file attachment out of the form and into a doc library, there is a qRules command SaveToSharePoint which will do the trick.
qRules is a plugin for InfoPath that works in the browser and doesn't require that you write code, but it is a code library.
Happy Thanksgiving!
