If you ever take flash drives anywhere, they can be left behind or fall out of a pocket. I recommend always creating a top level folder like below. That way, if someone finds it and plugs it in to be able to figure out who owns it, they can quickly see the answer and don’t have to go through any other private documents to get it back to you. The ~ at the beginning keeps it at the top alphabetically.  Of course, this is in addition to sticking an actual label on the drive! I’ve just had those fall off over time. The folder name is something that stays permanently, if the label comes off.
