When uploading an Office file to SharePoint, the SharePoint itself alters the file. As such, they differ binary and can no longer be considered duplicates when comparing their MD5 checksums.
This can be verified by uploading a file twice, download both files again and compare their binary values and/or checksums.

Other file formats (e.g. PDF, PNG, ..) are - by default - not being altered by SharePoint and work as expected.

Yes, that is possible. Under "Custom search > Other Filters", you can change the search parameters to include only folders of a certain directory level. You can exclude subfolders by selecting a "Maximum directory level" = 1, relative to the search path.

To keep scan times and memory consuption low, TreeSize aggregates its data on folder level. Therefore a rescan is needed if certain settings are changed.

We offer another disk space manager called 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. Here a rescan is not necessary in these scenarios.

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.

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.

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

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.

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

You can use the parameter /SCAN and specify the paths which should be scanned. For example:

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

You can also use the parameter /SCAN 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.

You can change your license key in the software directly at "Help > Change license key". A reinstalation the software is not required.

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.

Note that this issue should be fixed with TreeSize v8.0 or newer. Please update to the latest version if possible or contact us, should you still face this issue.
