Every file I view in Finder is reporting the wrong file size. For example if I'm viewing a 134,000,000 byte size file, Finder will say it's 134 megabytes when it should be closer to 128.8 megabytes. This is especially a problem with larger file sizes when I have to burn CDs/DVDs and I see the wrong file size, etc. But when I do 'du -sh filename' it reports the correct size in readable form (like 128.8 for 134 million bytes). How do I make Finder display the correct file size?
