EaseUS Todo PCTrans is a revolutionary pc software that allows us to transfer files between different PC or laptops.
It is also available in free version but it's featuree are limited , so i would recommend to use free version and use it and test how it works, if u are satisfied then you can go for premium.
Very nice computer application, nice hunt !
