Maybe everyone already knew this but me, but I did a restore point for my PC (due to an issue with a driver which is affecting Calibre). I thought when you did a restore point it did not affect your files, but it apparently does for the cloud synced stuff (at least on the cloud end)
My Copy folder deleted everything (I think because I had moved its location after the restore point I chose).
And my Dropbox folder deleted a bunch of stuff I had added to it as well.
Thankfully I managed to find it all (I hope) in the deleted items folders in Dropbox and Copy.
Technology has not be my friend lately.
