For most NAS systems, QuikFynd can be installed via NAS dashboard. But there are cases when it is not possible. For example if the NAS dashboard doesn't support any add-on applications. In this case, you can still copy QuikFynd to your NAS by using SCP (Secure Copy) and starting it by logging into your NAS via SSH (Secure Shell)
