There are many places that sell thumb/flash drives with more than 64MB. I have seen them all the way up to 512MB (if you're going for megabytes), or even ones that are 32GB (and I am pretty sure a gigabyte is bigger than a megabyte).
All USB flash drives (also known as thumb drives, pen drives, etc) are used as you would use the internal hard-drive inside your computer.

It is advised that flash drives are unmounted before being removed to ensure all writing is complete and to avoid possible corrupting of the flash drive.
