For some reason.
Dear buyers. I as a seller don’t have an obligation to babysit projects that were completed 4 years ago. Neither does fiverr. Which is probably the reason why you no longer can download 4-year-old attachments from the order’s page.
I also don’t have an obligation to let 4-year-old source files eat away at my disk space. It was 2017. You and I, dear buyer, were different people back then. The world was a different place.
Don’t go all casual into my inbox acting like we worked together more than once and the last project was completed yesterday. It’s your responsibility to manage the files you paid for properly. That includes downloading them in a timely fashion, storing them, and backing them up.
