Best way to transfer files from old SD card to new one?

[AC Question]

I have had a 64GB SD card in my Galaxy S5 for a while. Of course the capacity is actually 59GB and I have just about 56GB of files(music,pics,videos,etc.) I was recently gifted a 128 GB SD card that I've been wanting. Now,the problem is transferring all my stuff from old SD card to new one. Back when I had smaller cards from 4 even to 32GB,I could back it up to my PC hard drive. Since then,I still have the same PC/hard drive but with not enough space. What can I do?
