Disk Inspector is a disk scanning utility for Mac OS X. It scans any supported drive and generates a chart representing the file system usage.
Disk Inspector is addressed to those who want to keep track of what, where and how large files are stored in his Mac disk.
You can start managing the files shown on the chart immediately after they appear on the screen and doesn’t have to wait until the end of the scanning and analysis process.
Disk Inspector integrates with familiar system tools, so you can preview a file using QuickLook.
