Same Name Product but I need to format of files (Download)

[mdepresb]

I am beginer in PS.
I would like to sel only downloadable files and, for the same product, we will have to files format, with diferents prices each one.
Example: The Book X
Format : PDF Price 12,00
Format : TXT Price 10,00

The costumer bought PDF and TXT in the same cart.
After that he paid and he needs to receive the PDF downloadable file and the TXT downloadable file?

It´s possible to do wiht Prestashop, sending a email to the costumer showing bough products for download, automatically?

Thank you if I receive some help.
