An application that will help you find where all your disk space is
being used.

Mac Disk Explorer ingeniously searches all of your mounted drives
(including network drives), looking for large files, folders that may
have many smaller files, or even folders nested several levels deep.
It will find disk-hogging applications and other collections of files
that there is no other easy way to locate.

It runs on both PPC and 68K cpu's back to very early models. It is
also Mac OS 9 compliant and works with drives over 4GB.

Note: I have only tested this under OS 9.
