This requires linux (Ubuntu) other wise you are out of luck.
And it requires linux knowledge.
You could rename it to system.img then loop mount it under linux.
Code:
sudo mkdir /mnt/sys
sudo mount -o loop system.img /mnt/sys
cd /mnt/sys
nautilus .
Run that in a linux shell.
Then unmount once you are done reading and writing the image.
Code:
sudo umount -R /mnt/sys
Then copy the system.img to a windows machine again and if you have a samsung phone you could flash the image with odin packed into a tar.
Or rename it back to system.ext4.img then flash it how you were going to.
