I've been pulling my hair out at this task, which seems insurmountable. I have spent a lot of time consolidating all my past storage drives, and then doing it again, and now discover I have many duplicate copies. (You know that button that says save both? I clicked it too often)I'm not sure which of these duplicates to keep, because though the dimensions of the photos are the same, most of them have a small kb difference (i.e., 58kb vs 56kb). Does it matter which ones I discard? UGH! Feeling overwhelmed. Also, my logical brain wants to know why there is a difference in the saved files.
