The premise to your suggestion was that I wasn't sure how to do something. The premise to my statement was in determining a way to do something that meets with the criteria maximus06 set out, namely... why does he need to pull up a properties inspector in OS X, whereas Windows simply shows the combined size in the view pane when selecting multiple files. So, where you see me explaining something that sounds odd, I'm trying to express that without a properties inspector, simply shift-clicking on files in Windows is limited anyway (unless you get properties). It's neither here nor there, as neither of us are addressing the original post at this point (we're in some weird place where you're addressing how I answered the original poster without understanding what I was answering, which just makes for an off-beat conversation as I would never say what I said in any other context). Meh. Suffice it to say, both operating systems have flaws.

There is an excellent website called XvsXP, now called MacVsWindows.com.

Everything they list is in context, and well described. Here's a section on file management.
It's all one big Wiki, so we should all be adding to it if we see anything missing.
