Are you tired of running out of disk space and wondering where it has all disappeared to?

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