The Windows Explorer and the TreeSize drive list do show the space that is physically allocated on the drive while TreeSize shows the space that is occupied by all files under a certain path. Please make sure that you have the view option "Allocated Space" activated when you are interested in the physically allocated space.
Another possibility 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. If you want to get notified if a folder cannot be scanned, please open the options dialog (File > Options) and enable "Show error messages during scan" under the option page "Scan > General". Turning on the Option "Track NTFS specific features" in the Options dialog may result in more accurate results, because it racks e.g. hardlinks, but slows down scans. If a drive letter points to a sub-folder of a network drive, the allocated space (correctly) reported by TreeSize may also be much smaller than the physically allocated space on this drive reported by the Windows Explorer because possibly the whole drive is not accessible through the network.
Beyond the space that is needed for storing the files itself, additional space is used for storing management data like the File Allocation Table of the file system or the boot sector. It is not possible to free this space with TreeSize or any other tool. This is usually 0.5 - 2% of the occupied space.
Another possibility is that you are using a Software RAID - like Windows offers it - which spreads the data with redundancy over several disks. These disks will appear as one logical volume and the failure of a single disk will not cause any data loss. But for storing the redundant information additional space is needed, which cannot be used for user data.
A special characteristics of Offline Files can lead to wrong values for the allocated space of stub files. To avoid this, either ensure that the user which runs the scans has full read access to the scanned file system.
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.
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.
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.
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.
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 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.
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:
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.
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:
- Disabling Carbon Black for the system temporarily during install.
- 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.
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.
