Only customers with 25 or more licenses are able to download the MSI installer in our customers area.

An unattended installation is also possible using the normal installer. Please find more information on this in the manual.

The user who should use TreeSize needs to have read access on the folders that should be scanned, or alternatively the user must be permitted to request the Windows backup privilege, which is the case by default for administrators. Using the Windows backup privilege TreeSize is also able to query meta data like size and last change date. It may be necessary to explicitly run TreeSize "as administrator". User do not need read access on the file content unless you want to use the TreeSize duplicate file search with options that take the actual file content into account, and not only the meta data of the files.

Starting with Windows Vista / Server 2008, Microsoft introduced "Client Caches" with the SMB2 protocol in order to speed up queries about gathering file and directory meta information on network drives. This approach also helps utilizing the available network bandwidth more efficiently. However, these caches always return an incorrect value for  NTFS hardlinks (always shown as "1"). The responsible caches can be disabled with the following steps:

  1. Run "regedit.exe".
  2. Open the path "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanWorkstation\Parameters".
  3. Choose "New > DWORD value" in the right click menu and set the name to "FileInfoCacheLifetime" and the value to "0".
  4. Restart Windows

After these steps, TreeSize should work properly with hardlinks. For further information about client caches, please visit https://technet.microsoft.com/en-us/library/ff686200(WS.10).aspx.

Yes, this is possible. 

Please go to the 'Help' tab and click on 'Check for update'. Doing so will check if there is an update and bring up a notification window stating the result of the check.

The checkbox at the bottom of this notification allows you to choose whether to 'Check for updates regularly'.

Read this knowledge base entry to learn how to disabale the automatic check for updates or the "Check for updates" button programatically.

Open the Treesize File Search, enable only the "Advanced Search", and define a filter on the right for "Name matches Regular Expression" and one of these patterns:

 [^[:print:]]  if you want to treat all non-ASCII characters as invalid (which would e.g. also treat German umlauts as invalid)

 [^\P{C}]  if you want to treat all non-printable Unicode characters as invalid
 
It can also make sense to search for files containing the non-breakable space (Unicode NOBR U+00A0). To find them, use the pattern [\xA0].

To search for specific characters like percent and ampersand use the regular expression [&%]. You can find more examples on searching with regular expressions in the manual.

You can get rid of unwanted characters using the bulk renamer of TreeSize.

You can change the behavior by enabling the setting "Tools > Options > Scan > General > Follow mount points and external symbolic links to directories".

Symbolic links are marked by Treesize with a small arrow on the folder icon.

This issue was introduced with update KB4019472 for Windows 10 Version 1607 (Anniversary Update) and Windows Server 2016 and KB4016871 for Windows 10 Version 1703 (Creators Update). Please note, that newer cumulative updates like Windows 10 version 1709 would also contain this update.
A full list of cumulative updates which contain or replace KB4019472 can be found in the Windows Update Catalog in the 'Details' tab.
KB4016871 can be found here.

The error only occurs with the 64bit version of TreeSize, not affected is the 32bit version of TreeSize.

Since V6.3.6 TreeSize is compatible with Windows 10 and Server 2016 with update KB4019472. Customers with valid maintenance can download the latest version of TreeSize, which is compatible with Windows 10 in our customer area.

Do not install Windows 10 Update KB4019472 if you intend to use an older version of TreeSize.

Die Funktion "Auf Update Prüfen" lässt sich auf 2 Arten deaktivieren:

TreeSize mit speziellem Kommandozeilen-Aufruf ausführen

Durch den folgenden Kommandozeilen-Aufruf der Treesize.exe wird die Funktion deaktiviert:

TreeSize.exe /NOGUI /ShowCheckForUpdate False /SAVESETTINGS


Anpassen der Konfigurations-Datei ("GlobalOptions.xml")

Dazu müssen Sie die XML-formatierte Konfigurations-Datei von TreeSize editieren. Diese Datei liegt Standardmäßig in folgendem Pfad: "%APPDATA%\JAM Software\TreeSize"

Bevor Sie die Datei editieren versichern Sie sich bitte, dass TreeSize auf Ihrer Maschine nicht ausgeführt wird.

Bitte öffnen Sie die Datei "GlobalOptions.xml" mit einem Texteditor (z.B. Notepad) und suchen Sie darin nach folgendem Eintrag:<ShowCheckForUpdate>True</ShowCheckForUpdate>

Bitte ändern Sie hier "True" in "False" und speichern Sie die Änderung.

The "Check for Update" button in the "Help" menu can be hidden in two ways:

Running TreeSize with special command line options

If you execute this command line after the installation, the "Check for Update" button will be no longer available:

TreeSize.exe /NOGUI /ShowCheckForUpdate False /SAVESETTINGS

Please add the full path to TreeSize.exe, e.g.
"%ProgramFiles%\Jam Software\TreeSize Professional\TreeSize.exe"

Please note: Use the following command line call to deactivate the automatic check for update:

TreeSize.exe /NOGUI /CheckForUpdateOptions\CheckForUpdatesAutomatically False /SAVESETTINGS

Deploying a configuration file

First you need to edit the XML-based configuration file of TreeSize. The configuration file is located at the following path by default:

%APPDATA%\JAM Software\TreeSize Professional

(Please note that %APPDATA% is an environment variable that will be resolved automatically by Windows if it is entered in the address bar of the Windows Explorer.) 

Before proceeding, please ensure TreeSize is closed.

In the folder above, you will find a file called "GlobalOptions.XML" Please open the file with a suitable text editor (Notepad, Notepad++,...) and search for the following line: <ShowCheckForUpdate>True</ShowCheckForUpdate>

Please set the value "True" to "False". If you start TreeSize again, you will notice that the "Check for Update" button is no longer available.

Please note: In order to deactivate the automatic check for update in the configuration file change the following value from "True" to "False"
<CheckForUpdatesAutomatically>True</CheckForUpdatesAutomatically>

There is no TreeSize App for Android. But you can scan your mobile device using the TreeSize Windows desktop app, if your mobile device is connected to your PC via USB and is unlocked. For more details on this subject please visit our web page.

As an iOS protects its internal file system from running apps, an application like TreeSize wouldn't be possible for iPhones. You may use "Settings > General > iPhone Storage" the get a rough estimate what takes up the space on your iPhone.
