Infuse3 streaming or download?

Hi before purchase, I have a question. I have a iPad 16gb, and 5gb free. I can see a mkw file from my NAS (8gb) without the iPad crashing?

By default, Infuse will stream the file without downloading it.

You can however choose to download the file by tapping the ‘Download’ option found by tapping the ‘More’ button on the ticket view.
