WinDirStat: Windows Directory Statistics

Great program!! Very useful!
For very large filesystems it would be very helpful to be able to run an analysis, save the results (binary form) and open it later without re-running the analysis. This would be great for before/after comparisons as well as track progress.
Another option could be to export the results in database format for a broader array of off-line analyses.

I agree with gskala. the one add would be an export capability (binary, as gskala suggests, or exportable to, say, Excel), or alternatively a way to print the entire display.

Vote for "Saving the reports" feature. Sometimes you just need the rough picture what was eating your free space.
