I am copying files to a CD. Now, there are two things going on here that piss me off. First of all, when I copy files to a CD in OS X, it tells me when it is full. On a Peecee, I have to guess, and make a new folder that will add it up for me. So there's that. Luckily, I know about how much data a 700 MB CD holds (about 650 MB).
But then, there's this:

This is annoying for two levels. First of all, this is completely cryptic. Files I didn't know existed will not be written, but it won't matter. THEN WHY TELL ME?!
Second, even though I continually checked the "use this answer every time" box, every time I did a new copy, it asked me the goddamn question again. You mean, there couldn't have been a "use this answer always for now and forever option"? That would have made my life a little easier.
Apparently, that's not the business Microsoft is in.
