New imported raw file overwrites existing file
I had a very strange thing happen. After I imported raw files into one of my folders many of the newly imported images replaced previously imported photos, including the metadata. The older pictures are all gone and overwritten with a newer photo, both in LR as well as on the harddrive. I could literally watch the images change on the computer screen.
Can anyone explain, please. Looks like the older files are all lost, but I want to avoid this form happening again.
I have attached 2 photos to show the screen before and after this overwrite.
