About Baseline
Where has all your disk space gone? Baseline makes it easy to find out.

As well as telling you how much space each file or directory takes up on your hard disk, Baseline allows you to compare your disk against previous scans, to show you what’s changed.

You can view your files in a list, browser, or graphical TreeMap view.
You can opt to only view the changed items, so you can easily see what’s taking up the space you used to have free.

You can also delete, compress, and archive items, and empty the trash directly from within Baseline, making tidying up your disk a snap.
