Best Way to Copy a Mass Amount of Files to Another PC?

[ThatCrazyShaman]

# of files doesn't equal the time it takes to transfer them over. What is the total size of it all?

Buy a flash drive or external hard drive matching the size of total number of files you want to transfer and use that.

I'm not actually worried about time it will take, but about whether my computer would be able to handle it. In total, there's probably at least 140GB of stuff to be transferred, assuming that I don't delete anything beforehand. My computer is very fidgety, so I'm concerned that trying to do it manually would crash it.
