Yes, more than one NAS system may be added to your QuikFynd account. You only need to create one QuikFynd account and link multiple devices to it. Each NAS runs its own instance of the QuikFynd search server. You can choose the NAS device that you want to search by selecting the Group it is part of from the user interface. Since QuikFynd is licensed on a per user/per device basis, you will need to buy a different subscription for each NAS you want to connect. For example, if you have two NAS devices, you will need to buy two licenses of QuikFynd PRO subscription. You can continue to use QuikFynd Lite for free.
