Every hard disk is too small if you just wait long enough. TreeSize Free
tells you where precious disk space has gone to. It can
be started from the context menu of a folder or drive
and shows you the size of this folder, including its
subfolders. Each folder can be expanded in Explorer-like
style to see the size of its subfolders. Scanning is
done in a thread, so you can already see results while
TreeSize Free is working. The results can be printed in
a report.
