I was recently playing with the settings in the DSi and noticed something. In the data management screen, you have 1 save file for every game you have downloaded. This is unlike the wii which saves 1 file of the actual game and 1 file for any game saves. So that leads me to believe both types of files are included in the 1 file on DSi. So this is my question, if you delete that one file from a DSi for say memory purposes that will surely prevail in the future, is your game save deleted with it?

Yes

Most likely. Delete the game, delete the memory.

Well this really sucks then!!!!! I only have like 300 blocks left which won't last for too much longer. At least with wii the game save still remained intact. They had BETTER get an SD menu-esque system going on DSi real soon!

It's as simple as moving it to your SD card. Then your save data is intact. When you want to use it, grab that file off the SD. I'm pretty sure most games don't even use the save data.

you could even back it up to your computer or something if you were that desperate to preserve your games/saves for all eternity. you'd just have to be careful to label your folders carefully so that you knew which game files went to which DSi.

Could even use the same SD as your phone/camera/wii if you wanted to save cash!

You can't transer files to your SD Card.

Uhm, yes, you can....
Just open data management and touch "Copy" on a game/app and it will be copied to the SD card.

@ilomoga you can, but does that save the saved data with it too? and if so i wonder if you could extract the save data from the game itself?
