A few days ago I decided that I needed to delete items on the computer after backing up what was useful.This included backing up some family trees on to a stick. All was well I thought until I opened Family historian this morning and to my horror it was empty I then remembered thinking it was safe to do so,I deleted the backups that automatically save when I close the tree. Lucky for me I hadn't emptied the recycle bin and was able to return them. Years of work would have been gone. I had about many trees on the go and backed-up all but 3 of them intending to do that another time. Now I have to go through everything in the recycle bin to see what else should not be there.
