How to move storage from computer to laptop?

I'm getting a brand new MacBook Pro sometime this week to save my mom So MUCH ROOM on our ( family ) computer. I could figure out how to get my movies, songs and apps on there from iTunes but i might not be able to get something like minecraft or photos on there

There's a possibility that I might but computers can sometimes be mean to me and not work so it would be much appreciated if you could help me out. If ya can't I could go to extremes and call up my uncle ( he works with computers ) and have him help but I'd probably figure it out by then.

sry to ramble on - I need help.

Get a 16g [or higher] usb stick and transfer your files to it and then just put them on new computer.
