Sorry 4 the bad title couldnt sum up the problem. So i want to burn a 4.37gb .iso to 4.38 dvd-r. When i go to computer and look at the dvd-r and it say 4.37gb of 4.38 is free. But i would think thats no problem because there is just enough room but when i try to burn ( using windows explorer) it says i need an additional 320kb:confused: can someone help! thanks in advance!
