All of our products are being developed in Delphi or C#. Although we use Log4Net with some of the components, they are safe to use, because the reported vulnerability applies to Log4J only.

None of our applications depend on Log4J or any other Java library and are thus not affected by this vulnerability.

This applies to all versions and editions of our applications (TreeSize, SpaceObServer, SpaceObServer WebAccess, HeavyLoad, SmartPOP2Exchange, Exchange Server Toolbox, SpamAssassin in a Box, SpamAssassin for Windows, SmartCallMonitor, SEPA-Transfer, ServerSentinel, and ShellBrowser). It is recommended to always use the latest available versions though to benefit from the latest patches, improvements, and features.

There is no need to reinstall TreeSize Free in order to change the setting for the Windows Explorer's context menu.

On the 'Options' tab, you can simply change the option at runtime.

Since Windows Vista and later, Microsoft enforces more strict security rules on the operating system. One side effect of this is that you may not see your mapped network drives anymore (Windows 8 and later), or they all appear disconnected (typically in Windows Vista and 7) in all applications that run with administrator privileges.

This is because Windows uses different user environments for non-elevated and elevated processes. There are some workarounds to gain access to those network drives anyway:

  • Do not run TreeSize as administrator unless it is truly needed.
  • Manually enter the UNC path (e.g. "\\server\share") for the network drive into the path drop-down list or target selection dialog and press enter.
  • Map the network drive in the context of the administrator using an elevated command prompt (run CMD as administrator). You can list the mapped drives using net use
    Type net use /? for more instructions on how to map the drive.
  • [Professional/Personal only] Use the "Map network drive" or "Add drive or UNC path" dialog from the Drive List menu bar.
  • [Not recommended because of security bypasses!] Enable "Linked Connections" as described here.

Yes, TreeSize Freee may be used in commercial and enterprise environments. TreeSize Free has the limitation that it cannot scan network drives in Windows domains, this is only possible with the Professional edition.

However, please consider purchasing a few licenses of TreeSize Professional to support the further development of all editions.

One possibility why the total size displayed by Tree is that not all parts of the drive could be scanned due to access restrictions. Therefore it is highly recommended to run TreeSize as administrator.

Please make sure that you have the view option "Allocated Space" activated when you are interested in the physically allocated space.

Another possibilty has been introduced with Windows 10 version 1903, the system reserverd storage. This space occupies about 7 GB by default and is used by Windows exclusively. It is not visible to other applications and currently not represented with the scan.
