a have a pivot table with these data inside:
Selecting the "B" folder, I'd like to see not only the pairs 1/B and 3/B but also the pair 1/A, thus all the occurrences of the photo/folders where a particular folder is at least one of the folder in which a photo is stored.
Hope it's clear, if not pls. tell me and I'll retry to explain much better.
ok, what about managing these data with a pivot table?
I've added it to your sheet, but when I select the "A" folder, it returns only the "A" rows and not the pair 1/B
