How to delete save file for ACNL?

This is not me saying that I have accidentally deleted my save, this is a case of me wanting to manually delete a save for Animal Crossing New Leaf for the purposes of starting with an entirely fresh/new game. How do I go about doing this?

In order for us to provide better support, we need to see the log generated by citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File

What platform are you on? Android or desktop?

Desktop. Windows 10 specifically.

Right click on your game in Citra, then select Open Save Data Location. Your save data will be in here.
Some games also make use of extra data for save data, so Open Extra Data Location should get you there as well.

Right-clicking doesn’t do anything, Open Save Data Location doesn’t pop up. Nothing pops up when I right-click.

Are you sure that you’re right clicking it in Citra’s game list?

I don’t have a games list, I just load my ROMs directly from a folder I keep them in using File → Load File → then the ROM itself.

Please set a game folder then.
