The last access date of a file is maintained by Windows. Since Windows Vista/Server 2008, Microsoft disabled the automatic update for the "Last access" date by default to improve system performance on NTFS formatteddrives. Because of this, the date won't be updated anymore if a file content is changed for example. That is also the reason why the last access date isn't a good indicator anymore for recent usage of a file.

For more information, see the MSDN homepage.

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.

TreeSize v8.3 is compatible with:

  • Windows 11
  • Windows 10, version 1607 or above
  • Windows 8.1
  • Windows Server 2022
  • Windows Server 2019
  • Windows Server 2016
  • Windows Server 2012 R2
  • Windows Server 2012

We offer versions for older Windows versions and for 32Bit operating systems for download in the customer area:

  • TreeSize v8.1.4 for Windows 7, Server 2008 R2, and 32bit/x86 systems
  • TreeSize v7.1.5 for Windows Vista and Server 2008
  • TreeSize v6.3.7 for Windows XP and Server 2003

For these outdated versions a trial download is not available.

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.

For V8 you need a new installation key, you will receive this key after a login in our customer area.

The easiest way to install the update is to use the integrated update function: Click the "Check for Updates" button in the "Help" ribbon bar.
