How to format a USB flash drive with High Sierra?
I probably have a very simple question. I have a USB flash drive that I have some data on that I don't need. It's currently formatted for Windows. I no longer have a Windows PC, just my iMac running High Sierra. I want to format the flash drive to work fully on my iMac. Can someone point me to an article which just explains how to do this? My main question is, when I erase the drive using Disk Utility, what do I choose to format it as? Thanks.
