In order for Roon to see any files from the Sony, the Hap-Z1ES must present these files to the network via a shared folder. I'm not sure reading the description of the HAP if it has this capability or if it is capable if it has been configured properly.
I see there is special software to move files to/from a PC, so you may need to manually pull the files off, and copy them to a place Roon can get to them.
