I am looking to buy a larger memory card so that I can start building a library from games bought online. I'll likely go to the 16GB card even though it is extremely expensive - actually all the cards are. So what I hope to do is backup the original card (4GB), then restore it on the new card (16GB). So all the old content is on the new card.
Now I want to clear out the old card and keep it in my back pocket to load new games/etc. once in a blue moon - maybe to focus only on a couple games during vacation or other reason.
Q: What is the process for clearing out the 4GB card so I can start loading new stuff later? Do I use Content Manager's Format option?
Q2: Is it even possible to have more than one memory card active of a single PS Vita console? I assumed Sony would allow you to have as many cards as you like as long as you don't exceed their current 100 application limit and they are tied to a single Vita for DRM compliance.
