Compatible photo files on Synology NAS

I am an amateur photographer, and I use Fujifilm. Fujifilm RAF (RAW) files are not shown in Synology photos (a friend of mine tried it out) and WD Mycloud does show them. So, no matter how I try to switch to Synology, old faithful WD comes up with a trick in its sleeve.
