Brand new folder "system volume information"

[sludgeguts]

Just noticed a new file pop up when I look at the files on the card.
I'm sure this wasn't there a couple of days ago and noticed it for the first time yesterday.
I've just inserted a brand new card & ran the cam & noticed this file has appeared on the card.

I mean, what IS system volume information & why has this folder suddenly appeared?

What OS are you using? It means the card was inserted into a Windows system at some point.

Win 10.
I've noticed the same folder has appeared on a portable hard drive I inserted as well.
