Try to backup your game saves to your PC hard drive on a regular basis because you may erase a game and not have a backup in case you want to play that game once again sometime in the future. And I recommend doing this at least once a week, more if you play your games more frequently. Don’t take out the R4 DS from the Nintendo DS console each time you want to add files to the micro SD Card. Simply push the micro SD card with your finger and it will “pop out” of the R4 DS card slot.
