Restoring deleted/lost Save to my 3Ds Pokemon Sun

[Dino6347]

This is my first time on here and I wanted to see if I can get any help restoring a lost save file I had for Pokemon Sun (digital version). I don't know how I lost it, I might have deleted it years ago and it could just be gone forever is what I think but I figured its worth a shot trying to find it. I have the original 3ds sd card backup on my PC. I found some lost SAV files with Disk Drill and another SAV file on my backup folder in the sd card. Ive tried using Checkpoint methods Ive seen online but I keep getting corrupted save message whenever I open the game. My question is how do I know which one is my pokemon save and how to properly transfer it to my digital copy of Sun?

Note: I have a modded 2ds with a different sd card. its the original one I had the game on

the first image is the recovered SAV files I found and the second image is the SAV from the backup folder. The date on the second image is the same date I started the game 6/30/2017. (Im not sure if that might be it) Im open to any help at all.
