Mac OS High Sierra
I upgraded to 10.13.1 today. When the upgrade was finished, to my dismay, my Documents folder was completely changed-- everything I kept in it was gone and moved to a folder called Recents. I was horrified; I was backed up on Time Machine, so I was able to return everything to the Documents folder. What is this Recents folder? There's no mention of it in any info on what's new with this upgrade.
