Xinorbis 3.6 - Supports Windows 98/ME/2000/XP/Vista - Free software
 
Xinorbis is a simple but powerful hard disk analyser.

Using a sophisticated mix of graphs, tables and tree displays, it gives the user a complete overview of the contents of a hard disk (or directory). It makes it easy to see the contents, structure and file distribution and file composition of a whole hard disk, directory, or mapped network drive. Includes full report creation.

 
Features include;
 
 analyse a single drive / directory or merge several together in one report
 complex report generation, with export to HTML, ASCII or XML
 save reports and compare them to see how the contents has changed
 all information displays are completely resizable for ease of viewing
 XP style support
 improved speed
 shell support, scan a directory through explorer!
 
Xinorbis is now available for download with an installer, the recommended option, or as a zip archive for expert users who want more control; such as installing Xinorbis on to a USB flash drive. 
 
Several additions have been made to Xinorbis to make it operate more efficiently as a “portable application”, for more information see the help pages.
