Recursive Time difference for blocks of filename and size (duplicates)

[anmac1789]

hey guys! it's me again back with another question regarding excel functions. This time I have a request for a function that seems a bit...involved. How can I create a list like the below one ? For the difference in time, I am using a formula such as =text(abs(time1-time2),"hh:mm:ss") but again, I'd like to do this for every row or 'block' that has a matching filename and size. How do I do that ?
