I have gone from using a WBFS partition to NTSC, so have converted all my WBFS file games to ISO files via WiiBackup. But now all the game files are a massive size and dont have enough space to fit them all on my external HD. The thing is when i load the folder with all my Wii game in through Wiibackup, they show up as smaller sizes, and say that all my games are only 53GB, yet on my actual external HD they are taking up a massive 150GB. How do i get the file sizes smaller with NTSC iso files??
