Not sure. The blank CD I have here offers 702 meg.
If I look at the properties screen for my shrapnel dir, it says it takes up 741 meg (777,617,052 bytes), but that that's 786meg (825,196,544 bytes) on disk. Confusing. I assume the "size on disk" figure is a product of Windoze' bloaty file system, and that the former number is the one that would apply if I were to copy the files to a CD.
What I will probably do is leave out (or zip up) a number of the less-used races.
I just thought this would be an interesting thread for anyone trying to save a little space.
Also I think I have screwed up my sounds folder.

Anyone know where I can download the enhanced sound mod? Doesn't seem to be on the Gold CD.
