Oh no, that was the folder that contained your only copy of the human blueprint. I think it is only one per customer...
Anyway, to truly know what it was and/or what it was for it would help if we knew what device you had? It could be just about anything but the first thing that comes to mind is a health tracker, where it might save a screenshot of the data it collects rather than actual data of some other kind. One of my financial apps does this.
Otherwise if it something needed by an app you've installed it will repopulate itself when it needs to store information.
Start a conversation and we can go from there.
