RidNacsRidNacs is an easy to use and fast disk space usage analyzer. It scans your local drives, network drives or single directories and displays the results of the analysis in a tree view with a percentage bar.
This gives the user a quick and easy way to identify the largest directories and it's very useful for cleaning up the disk. The result of the scan can be exported in different formats (XML, HTML, CSV, TXT), so it could be printed or compared with future scans.
Besides all these benefits RidNacs has an outstanding scan performance and it scores with a small memory footprint
