I've been trying that- none does as I or the OP wanted. I want it to display the size of all the items inside a folder when I am at the folder level.
If
'D:\porn" contains 1TB of porn in 1024 files
"D:\work" contains 2MB of word docs in 50 files
"D:\music" contains 1GB of music in 100 files
When I point explorer to D:\, I want to see folders for porn, work, and music, with 1TB, 2MB, and 1GB next to them. The Vista columns seem like they would work, but they aren't. I'm running Ultimate, updated recently. There used to be a utility for XP that did this, it was called FolderSize.
