Asking as someone not as familiar with the research community as I'd like to be, what are DOI files, what advantages do they have over PDF/PostScript, and are they common?
It's not a file format, it's a digital identifier. The APA can explain it better than I can:
"A digital object identifier (DOI) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the Internet. The publisher assigns a DOI when your article is published and made available electronically."
So you can access a journal article by going to http://dx.doi.org/DIO-GOES-HERE. doi.org doesn't host files, just resolves them to the current and correct location. For example the DOI number for the first paper in TFA is 10.1007/11427186_42 so it can be accessed at http://dx.doi.org/10.1007/11427186_42
I'm surprised the author didn't search for DOI links.

You know the DOI you know where you can find it.
DOI isn't a file format. It's an object identifier for papers like ISBN is for books.
TIL about DOI :)
