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.

What´s New in version 2.5.1:

• Increased speed when expanding many folders using the new "Expand" menu and many files are involved.
• The progress of a scan is now shown in the Windows 7 taskbar.

What´s new in this version 2.5:

• TreeSize Free is now able to show the NTFS compression rate in the directory tree. This adds the main feature of our discontinued tool NTFSRatio.
• A new option allows to show compressed folders in blue color. Folders that are only partially compressed will be shown in dark blue.
• It is now possible to rename files and folders in the directory tree. This can be done by using the right click menu or by pressing F2.
• A new menu "Expand" in the main menu and the right click menu of the root folder which allows to expand all subfolders up to a certain level.
• A scan can now be stopped using "File > Stop Scan".
• The layout of the main menu has been revised.
• The support for Windows 2000 has been dropped because Microsoft dropped it in July 2010. TreeSize Free V2.4, which is compatible with Windows 2000, will remain available on our website.
• A few minor improvements and bug fixes have been incorporated.
