Software that breaks down folder size?

[UnderOpenSky]

I used to have a piece of software on an old machine on 98 or 2000 which added extra functionality to the right click, properties, when clicking on a folder, giving you a nice pie chart of the sub folders size. Unfortunately I've forgotten the name.

Anyone know what I'm on about and if there is an equivalent for Xp?

Not exactly what you're after maybe, but a treemap is a nifty way of visualising folder and file sizes:

Graphical results will look something like this for each folder / large file:

Space monger should do the trick, but there are quite a lot of similar programs out there:

windirstat is the best thing that does this, and it is free.

There's a freeware version of SM too.

I don't know which one is best coz I've not tried them all.

Most of the major ones are listed, along with links here:

Find the one you like and go with it.

I used to use TreeSize.

SpaceMonger is good if you're doing a whole hard drive.

I like SequoiaView.

Treesize used to be good, but the newer versions are bloated and not free.
