Sentence meaning

What do you understand/interpret from this sentence that I received by email:

Here are some document files on your interest.

Also, is this sentence correct?
I don't clearly understand what a 'document file' means here.
Does the writer just mean 'some documents' or 'some files'

I think she meant: here are some documents that are related to the topic of your interest.

eg Here are some documents that will interest you.
eg Here are some documents concerning the topic you are interested in.
eg Here are some documents related to prostate cancer.

eg Here are some documents related to your field. (Sounds like you are referring o some academic filed, eg medieval history.)
