My Email exports with text format are hard to read. What can I do?

When exporting in a text format, the table is indented with space characters. In order to easily read it, a so called monospace font must be used to display it, e.g. the font Courier New. You can configure your Email client accordingly.

For Outlook 2016 you find the settings under "File > Options > Mail > Stationery and Fonts > Composing and reading plain text messages". Choose a monospace font like Courier New here.

When scaning my SharePoint server, a large library or folder is missing. Why?

By default, Windows does not enumerate folders via WebDAV that contain more than 20000 (20k) elements. Microsoft created a knowledge base entry that covers this topic: https://support.microsoft.com/en-gb/help/912152/

The workaround in short is:
Change the value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters\FileAttributesLimitInBytes to 1000000000 (that’s nine zeros) and restart your computer.

Why do the exported XML files do not contain any files?

If we would include also the metadata of files, the XML files would grow by factor 10-20 and reach a size that cannot be handled reasoably.

If you need history datas and growth report on file level, we would likew to recommend our product SpaceObServer. It regularly collects the file system information using a background agent and stores it in a SQL database, including size development and (optionally) all permissions. The reporting is faster and more flexible compared to TreeSize, because it is built on a database and collects data on file level. SpaceObServer offers advanced scripting capabilities through OLE Automation.

When I try to save a scheduled task, I receive an error message "Task credentials could not be stored". What can I do?

In order to store credentials for a task, TreeSize uses Windows' credential manager. However, the setting that allows to store these credentials can disabled by the Administrator, via group policy. In that case, creating new tasks is not possible.

You can change this setting by starting the security policy manager "SECPOL.MSC". Navigate to "Security Settings > Local Policies > Security Options" and locate the option "Network access: Do not allow storage of passwords and credentials for network authentication". Make sure that this setting is disabled, if you want to create an automated task.

I get a Certificate Error on start. How do I fix this?

Treesize.exe is digitally signed using an AuthentiCode certificate issued by VeriSign. One possible cause for this error is that the VeriSign root certificate is missing, so the certificate chain is broken. The Verisign root certificates are deployed through Windows updates.

There are only two possible resolutions if you want to use our products on that system:

  • Install the product using our installer, or
  • please make sure all available Windows updates are installed on this system.

In the unlikely case both options did not resolve the option, please point a Windows Explorer to “C:\Windows\JAM Software\TreeSize\”, right click on TreeSize.exe, select “Properties”, go to the tab “Digital Signatures”, select the item “sha256”, then press the “Details” button, then press the button “View Certificate”. Please send us a screenshot of the tab “Certification Path” of the dialog window which pops up then and a screenshot of the actual error dialog.

Is it possible to scan multiple paths at once, without having to select them one after another in the user interface?

Yes, that is possible with the command line parameters of TreeSize Professional.

You can simply add the paths at the end of your command line to specify which paths should be scanned. For example:

"C:\Program Files\Jam Software\TreeSize\TreeSize.exe" "C:\" "D:\" "E:\"

You can also use the parameter /SCAN can to define a text file, which contains a list of paths that should be scanned when TreeSize is started.
The text file should contain a simple list of scan paths, separated by a newline:

\\server1
\\server2
\\server3
etc.

An example command line call for this would be:
"C:\Program Files\Jam Software\TreeSize\TreeSize.exe" /SCAN “C:\scanpaths.txt”

It may also be useful to create a dedicated shortcut that executes one of these command lines. To this end, just create a shortcut to Treesize.exe, open the "Properties" dialog of the shortcut, and append the command line parameters as arguments in the "Target" field.

The GUI on our professional software does not show up when the security software Carbon Black is running.

It seems that Carbon Black is not compatible with the license management and anti piracy component that we integrated in TreeSize. Disabling Carbon Black when using TreeSize solves the problem. To do so, perform the following steps:

  1. Disabling Carbon Black for the system temporarily during install.
  2. Editing the permissions on the Carbon Black ‘Policy’ by adding a ‘Bypass’ action for TreeSize.

A similar problem has been reported for Lumension Endpoint Security.

How do I change the installation key?
You can change your installation key at "Help > Change installation key". Reinstalling the software is not required.

TreeSize 6.3.7 or newer does not start, crashes immediately, or cannot be installed on Windows 10.

These type of problems can occur, if the option "Force randomization for images" (mandatory ASLR) in Windows Defender is enabled, which overrides application specific settings.Activating this setting will disregard the compatibility information of the application and can cause the application to crash immediatly, or not start at all, as is the case with TreeSize.

To fix this, you can either disable this feature completely, or add TreeSize as exception to your ruleset in Windows Defender:

Open Windows Defender Security center and navigate to "App & browser control > "Exploit protection > Exploit protection settings". Under "System settings", you can deactivate "Mandatory ASLR", or use "Add program to customize" under "Program Settings", to deactivate this for TreeSize.exe only.

Other security software like Carbon Black may also be blocking Treesize or its installer.

Where do I get the MSI installer?
Only customers with 25 or more licenses are able to download the MSI installer in our customers area.

What are the minimum access privieleges that a user needs to run a scan?

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.

TreeSize shows incorrect number of hardlinks for files, stored on a network share. What can I do?

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