can an OLIVE OPUS 4 be a NAS / share files ?

perhaps someone knows, can an OLIVE OPUS 4 be a NAS for another streamer?
Can I copy my audio files out of the OLIVE and on to a NAS via Ethernet?
Or any other way (I was unsuccessful) 
You will probably find more answers here. There are quite a few pages, but some very knowledgeable Olive users on the site.
