Email Extension attatchment

[#1]

Dear Qlikview Extension developers,

I am developing an Email extensions, which opens the clients outlook application and sens a pre formatted email.

An example is show in this thread http://stackoverflow.com/questions/18869489/open-outlook-email-client-from-javascript

This works great, it allows me to apply html formatting in the email which gives great flexibility in the email itself.

However, I now want to attatch a document to my email which first needs to be created from the data in the extension.

Hope you guys can give some input. Below are 2 questions.

1. Am I able to load data into my extension and then write it to disk in a file format (whithout prompting the user), so that I later can grab the file I created?  (Does Javascript allow me to do this?)
2. Am I able to create an in memory file, and create a download link so that outlook can refer to that url?

          something like this: https://community.qlik.com/servlet/JiveServlet/downloadBody/7054-102-1-8985/QV%20Tutorial.pdf‌

Note, the extension is planning to be runned on qlikview server.

Hope you guys can help!
