This is one of the things I haven't figured out how to do yet on my mac. I miss this feature which was so easy in windows. Select multiple files and click properties and you get a file size count. If you do the same thing on a mac you get a number open for each file. If you need a cumulative total quickly its a pain in the butt to add each file. What am I missing here? Also, any way to display file size at the bottom of a finder window? When you click a file, it says "1 of X selected" and the amount of hard drive space free which is cool, but file size at the bottom would be nice to have.
