Need help with home-hosted cloud folder

I'm trying to set up something that will automatically sync files between an android device and a W11 PC that would be my mainly used PC. I have a separate drive I shared with Syncthing, but when I attempt to open those files on android, they seem to be encrypted, there's no file type and they get nested into several folders

Is there an easy way to change this behavior so it will produce a usable file on the android device?
