TreeSize 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 is working. The results can be printed in a report.

What´s New in version 2.6:

• If started as administrator, TreeSize Free is now able to calculate the size of directories you normally do not have access to, e.g. the folder 'C:System Volume Information'. This should lead to more exact results and does not break Windows security because files still cannot be opened. Please note that the Personal and Professional Edition are able to calculate even more exact results, by taking NTFS Alternate Data Streams and hardlinks into account.
• The option “Show Files in Directory Tree” lets you decide whether or not individual files should be shown in the directory tree.
• It is now possible to apply NTFS compression to a directory branch and to decompress a directory branch using the right click menu.
• Two buttons have been added to the toolbar that allow navigating forward and backward, like in the Windows Explorer.
• The operations 'Expand to level xxx' are now available in every subfolder's right click menu. A new option lets you decide whether or not the operations in the the 'Expand' menu will be applied also to the [Files] items.
• A few minor improvements and bug fixes have been incorporated and the performance has been improved.
