Hello Guys,

I have a Windows 10 Laptop, Android phone, Windows phone and an iPad. I would like to have a couple of selected folders that must remain in SYNC on ALL devices. Then a few folders on each of my mobile devices to be backed up on my laptop. Is there a way to achieve this using my WiFi (LAN) WITHOUT using Internet. I am aware of cloud storage solutions and we can rule them out. I need to get this to work with Free softwares that use just my WiFi router (without Internet) and to AUTOMATE this process. I don't mind if the iPad is left out for this. No cables, no internet, please.

Thanks for your help.
