Girlfriend (27F) wants me (24F) to delete all pictures from my previous relationship

My girlfriend and I have been dating for a little over a year. I was with my ex (27F) for almost 6 years. We broke up last year, and I started dating my current girlfriend a few months later.

TO BE CLEAR, I don't have the photos on my phone. I don't have it on my laptop/computer. It's stored in the Google Drive of my secondary email. I don't even look at the photos. i was clear and upfront with her way early in the relationship. "Hey I dont have photos of my previous relationship on my phone, it's just in a cloud storage". But the topic came up again recently and apparently she has an issue with it. Also these are normal photos, not nudes. Nudes were deleted the very day we broke up.

My ex and I ended fairly amicably, she broke up with me. It was a clean break-up and overall healthy relationship, (even though I'm like 90% sure she cheated on me at the end). I don't see any reason to delete our old pictures. I was with that person for a quarter of my life. I don't think it's fair to make me delete 6 years of my life and pretend she doesn't exist. Memories and experience have occurred whether my girlfriend likes it or not. Again, to be clear, I dont miss her, or keep looking at it etc. It's just...there, in cloud storage. Doing nothing.

I also do photography as a hobby. And honestly I don't like deleting photos in general, doesn't matter if they're shitty ones, funny ones, or candids etc. I messed up once as a kid and accidentally permanently removed my family's beach holiday photos. Since then, I've very very rarely deleted photos. To the point i keep all my massive raw files even after processing and saving JPGs and I'm always struggling with storage space on my PC.

Anyways, I don't think it's fair for her to want me to delete 6 years of my life and pretend it never happened. Especially when it's harmless in storage that I don't even use.

But I feel like an asshole for not taking my current girlfriend's feelings into consideration. Yes, I understand if she might feel weird or upset but it's literally harmless, in storage. I could have easily lied but I was transparent about it.

TLDR: I was with my ex for almost 6 years, a quarter of my life. I keep our photos (normal photos, not nudes) in my secondary email's cloud storage. I haven't open it look at them, dont miss anything etc. It's literally just there in virtual storage. But my girlfriend doesn't like it. I think it's unfair to delete a major part of my life. Am I the asshole for not taking my current girlfriend's feelings into consideration.
