TreeSize Free 2.3.3 is a Disk Management product from jam-software.com, get 4 Stars SoftSea Rating, Every hard disk is too small if you just wait long enough. TreeSize Free tells you where precious space has gone to. TreeSize Free 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 Free is working. The space, which is wasted by the file system, can be displayed and the results can be printed in a report.
Simply execute the installer and follow the instructions. TreeSize Free can be uninstalled through the Windows Control Panel. All Windows version from 200 - 2008 are supported, including the server and 64Bit editions. Besides a normal installer a ZIP file with TreeSize Free is available, which saves its settings locally ans can e.g. be used on a portable USB Stick.
The following information is important. Provided are instructions and information which makes understanding of TreeSize and how to use it easier.
* The allocated space that Windows shows in the properties dialog of the drive larger than the allocated space reported by TreeSize Free. The Windows Explorer shows the space that is physically allocated on the drive while TreeSize Free shows the space that is occupied by all files under a certain path. Please make sure that you have the view option "Allocated Space" activated when you are interested in the physically allocated space. Another reaon for this difference can be that not all parts of the drive could be scanned due to access restrictions. Therefore It is highly recommended to run TreeSize Free as administrator. Turn on "View > Options > Show Errors Messages" to get notified if a folder cannot be scanned. Beyond the space that is needed for storing the files itself, additional space is used for storing management data like the File Allocation Table of the file system or the boot sector. It is not possible to free this space with TreeSize Free or any other tool. This is usually 0.5 - 2.5% of the occupied space. Another possibility is that you are using a Software RAID - like Windows offers it - which spreads the data with redundancy over several disks. These disks will appear as one logical volume and the failure of a single disk will not cause any data loss. But for storing the redundant information additional space is needed. On Thinkpad laptops the Rescue&Recovery feature may use a lot of disk space in the folder "RRBackup" which is not accessible to other applications.
* All folders which are visible in the window, will be included in the printed report. If you want a complete report, select the top folder and select "Full Expand" from the context menu.
* The indicator bars in the background, which can be selected to appear in the View menu, indicate the size of a folder relative to the scanned folders.
* You can use the CD-ROM cluster size to determine how much space a directory tree would occupy on a CD-ROM.
* By default the Windows folder "System Volume Information" is not accessible for users as well as Administrators (you can check this in the Windows Explorer after switching the hidden files to "on").
* Only file system folders can be scanned with TreeSize.
* "Access Denied" and other error messages are displayed by Windows and can be suppressed in the Professional version.. The license of this file & disk software is Freeware, you can free download and free use this File & Disk software.
