Three days ago I was tired and had too many things going on, and I deleted a bunch of files, primarily graphics and (irreplaceable) photos, believing until 15 seconds afterward, that I had them stored elsewhere.
Fortunately I know of, and have used in the past, the excellent GetDataBack. I ran it and sure enough I retrieved every lost image. All 238Mb!
Suffice to say I'm going out of my way to get many of these pictures stored online to insure against data loss.
