I got like 670MB of files and my CD has space for only 650.4 MB (that's what Easy CD Burner estimates). I don't feel like using a new CD for only 20 MB of files and it's also CD-R so I can't change the contents of that CD again. Is there anyway to store all of 670 MB on that CD? I have heard that you can store maximum of about 700 MB on this kind of CD-R...
