Oh, sure, DON’T answer my question…

Look, I’m running out of free space on my main SD card, and all my other SD cards already have content on them. I’m not about to delete all my save data, and I’m not planning on spending money on a new SD card. And since I don’t have any WiFi at my house, I can’t simply redownload games whenever I want. So I would really appreciate it if someone could PLEASE answer my question!!!
