Can you compare why samba client and NFS client are used differently?
For example, Why do I have to
mount a shared directory on a NFS client side, while I don't have to for samba client side?
In pcmanfm, why can I just type
smb://192.168.1.198 on the address bar of file manager, and connect to samba server, while I can't do similarly to access a NFS shared directory, or how can I?
