Yes, please see chapter "Installation".

Please make sure that the option "Create Statistics on File Owners" is activated in the Options of TreeSize. After the scan is finished please right-click on this user on the "Users" tab and choose "Limit to this user" from the context menu. You may also use the Custom File Search to search files of certain users.

You can specify the startup behaviour of TreeSize in the Options dialog. Or you can simply create a shortcut to treesize.exe on your desktop or the Start menu and add those drives and folders to the command line, separated with a space character.

Yes, in the Professional Edition you can use UNC names like "\\SERVERNAME\Share" to access a network drive by entering them in the drive combo box on the top of the main window. You can also use UNC names on the command line.

The free space is added to the pie chart if the root of the scanned drive is selected and the according option is activated in the context menu of the pie chart. In other situations (e.g. if a sub-folder is selected or the "Number of files" mode is active), it doesn't make sense to add the free space because the relationship between the free space and the other values displayed is wrong.

In the context menu of the topmost folder you may choose to hide folders below a certain size. To achieve this, right-click on the topmost icon (or use the "Expand" button on the ribbon bar), select "Expand > Hide Folders smaller than: XX MB".

TreeSize accepts wildcards in paths, simply tell TreeSize to scan \\Server\?$ in the folder combo on the top left or at the command line.

By changing the option "Follow mount points and symbolic links" in the Options of TreeSize, you can control if mount points and symbolic links should be followed or if they should be excluded from the calculations.

TreeSize can scan Linux/Unix servers using the SSH protocol (see "Scan Targets"). Alternatively, if Samba is installed and running on the Linux/Unix system, our tools can access a share on this system using its UNC name, e.g. \\ComputerName\ShareName.


If the file system on the Linux/Unix system is accessible through NFS, then it can be accessed if the NFS support for Windows is installed. For Windows 7 and higher (Professional / Enterprise Edition), please go to the Control Panel and activate the "Services for NFS" under "Programs and Features > Turn Windows Features on or off".
Then you can mount an NFS share to a drive letter using this command:
mount \\ComputerName\ShareName N:

It might be necessary to create the following registry values if you have trouble connecting the NFS drive:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default\AnonymousUidas DWORD with the decimal value 10011.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default\AnonymousGidas DWORD with the decimal value 10012.

Generally, you still need to be within your maintenance period to be able to update the product. If you are not, you can reactivate or extend it at any time.

The easiest way is to use the "Check for update" button on the "Help" ribbon bar within the program. The program then checks for the latest available version and installs it.

It is also possible to download the installer for the latest version of TreeSize from our customer area. The login details for our customer area have been emailed to you after the purchase and are printed on the license document. To upgrade older versions, simply run the installation file, the old version does not need to be deleted before. Your user settings will still be preserved during the upgrade.
