def and dsd files

I have some dsd audio files and dsf audio files that I am looking to convert into a format that is easier to access.  Currently, I'm using a 4TB portable drive through my Oppo BD103 but it will not convert these files. I was thinking about adding a Synology DS918+ with Roon Nucleus+.  Does anyone readily know if this would work?  If not I would love to hear some suggestions that do work.
