How to manage configuration files on Synology


I have installed OpenHAB2 on Synology running DSM6
Using SSH I can see that the package has installed itself under /volume1/@appstore/openHAB2
What is the best practice to access the configuration stored in on Synology from my Mac?

I guess that at least I need to be able to access /volume1/@appstore/openHAB2/userdata, /volume1/@appstore/openHAB2/conf and /volume1/@appstore/openHAB2/addons

maybe just move the directories to /volume1/public/openHAB2?
