Tool to display disk space usage details?

(I'm running Windows 2000).

My 20 GB disk is nearly full, and I'd like to know what it's full of (so that I can know what directories are worth archiving, zipping, or deleting to free up some significant quantity of disk space).

If I do "Properties" on various directories in Explorer, to see how much space is occupied by each directory and its subdirectories, this is too real-time-consuming (because each time I run it for one directory, I have to wait while it enumerates all the underlying files).

What I'd like is a tool that can:

*  Almost instantly (i.e. in near-real-time), display the amount of space required by files a given directory and its subdirectories

*  Or, run overnight, and build a map of all the directories on the disk, and present that data in something like a tree format into which I can instantly drill down to find the directories which take more space than they're worth.

No, I haven't tried Google to search for such a tool.

It's written in Java for the GUI but don't let that scare you.  This guy knows how to write fast Swing code.  And it feels almost like a native app with the widgets he's using.

Buy a bigger hard-drive, 20 GB is nothing.

Try sequoiaview ( see google )

I second .

Just me (Sir to you)

Free and does exactly what you want.

Hmm. I looked at Sequoia a few years ago and it wasn't ready for prime time. I like the new version though with the colored files, that's really handy to see at a glance what kind of files are clogging your computer.

But I still think spacemonger is just sleightly better because it shows you the directories without having to mouse over the files and when you mouse over a directory it gives you the size. I don't even know if you can mouse over a directory in Sequoia. I'm still guessing what the directory size is in megabytes.

I second the bigger hard drive.  Space is so cheap now, that unless you're (legally?) downloading CD or DVD sized movies on a regular basis, you can get a HDD 3-5 times bigger than the one you have now and just not think about it for a few more years.

SequoiaView is great.

Also generally to find out directory sizes in a dir you can use Total Commander: press alt-shift enter and it will scan all sub-directories and display their sizes.

I second JDiskReport, the Java app. It's definitely the best looking and fastest Java app I've seen in ages. Now, if only that guy released it's source....

JDiskReport looks good, like a powerpoint presentation with all sorts of almost useful information.

Spacemonger 2 looks great but it's been coming for WAY too long.

TreeSize ( may be what you're looking for.

Check out scanner from

It shows you at a glance what the biggest users of your hard disk are (and allows you to delete and uninstall files). It is also free, tiny and does not require installation.

Oh, and if you're wasting that much disk space, you might want to try DoubleKiller which should find any duplicate files you may have on your hard drive and help you delete them.

Another freebie, it's got a great UI and it's very easy to use.

Spacemonger 2 has been my personal example of the Second Syndrome Effect from the Mythical Man Month:

Try Ace Utilities.
It has a disk analyzer, and duplicate file finder

It is a great example.

Based on the screencaps he seems to have a *mostly* working version, but it's still not released, even in beta.

I don't know what's wrong with 1.1, 1.2, 1.3, etc. Why does he need to add all the features at once? It just seems silly.

I wonder if this could accurately describe what's happening to Microsoft with Longhorn.

I was about to suggest i.Disk... but you beat me to it Dmitri.

Hey, by the way Dmitri, long time no see! ;) Hope you and the fam are well.
