That is in case you have a slot on your PC (or reader). You put it in the adapter and then the PC. I dont use mine but I have the slot on the front of my case.

No problem. The adapter makes it handy for other things that use a media card as well. I have mine stored away and have never needed it. I dont plan on removing this media card from the BB unless there is an issue..
