Maybe this query can help you:
$ tracker-sparql -q "SELECT ?u WHERE { ?u a nfo:FileDataObject. FILTER
(NOT EXISTS { ?u a nie:InformationElement. })}"

It gives you everything that is a File but doesn't have any
interpretation (the extractor didn't tell us what it is).

Well, this doesn't help. There is no such files.

Here is the output of tracker-info which have only basic metadata because the extractor failed:

It is indeed a nfo:FileDataObject

My current command only check for some files that I know to have the property nie:hasPart. it's what I am checking, but that wouldn't do for any kind of files.

I would really like a tracker:error field so I could get the list of those files easily
