How to recover games and saves from old SD Card after initializing?

[server404]

So there was an error on my switch and I decided to initialize it to try and fix it, but before I did that I copied the nintendo folder on my sd card to a hard drive in order to save my games and saves. After setting up the console again and adding atmosphere, hekate, etc. I tried moving the nintendo folder back to the sd card, but whenever I turn on my switch it tells me that I have to erase the data on the sd card in order to use it. I tried finding out which folders the games were in but they're all encrypted since I downloaded them from tinfoil. Is there any way to figure what games are on my sd card in order to redownload them or am I screwed?

Your game saves are stored in user partition (either in emmc on console or emummc on sd card), not in nintendo folder.

Also if you are running custom firmware, the nintendo folder you copied is only for ofw. The one for emummc is in sd:\emuMMC\RAW1\Nintendo

To decrypt nintendo folder you can use this tool, it hasn't been updated in years so idk if it still works.

If you used partition based emummc then the data is gone, emummc is stored at the end of your sd card space and is overwritten when you created a new one. Since it's a raw partition and the user partition is encrypted, idk if there's any data recovery tool that will work with it.

If you used file based emummc then there's still a chance you can recover your game saves, scan the sd card with any data recovery tool, you might be able to recovery your old emummc files in sd:\emuMMC\
