It does calculate the total and counts the disks, but it is not clear if you only have a couple of files selected as I did. So a side note stating that it will span multiple disks, regardless of what is selected might be an idea.
I have revisited this feature again today, and the pull down that suggests that you can burn nested folders did not seem to work. I browsed to a folder (left list) containing many folders, tried the pulldown for two levels but the burn logo never hightlighted as functioning. Is there something I am missing here?
The burn button works when I select the files individually or as a select all files.
