With interfaces! ;)
You could create a new interface (and probably some wrappers) with all the required file functions you need and replace the actual type with that in your code. The original struct will implement those instantly and you could re-write the function in your test.

Example:

(But I would not recommend to start the interface name with I... it's not java or php. :) )
