By the way, everything that you can do on the computer, like play a game or browse the internet using Firefox or whatnot, is possible due to the memory space your computer has. That means that you can transfer nearly everything. The stuff you can't transfer are those ones that don't work when you transfer the files because its a copyright, and that if that could happen, then that program would be free everywhere.
Basically, everything is transferable, but not everything can work after transfer.
