Which access rights / permissions does a person require to perform a scan on a drive or share?

Basically a user requires the right to list the folders contents and to read the attributes.

However, being a member of the Administrators group is sufficient for TreeSize to scan the whole disk on a standard Windows network/installation.

How do I unlock or activate the trial version? I purchased the full version of Treesize but can't find a place where to enter the installation key in the demo version.

You have to download the full version of the software from our customer s area.The login data can be found in the e-mail or in the printed license which you have received after the purchase. In case that you do not have your login data any more, you can request them to be sent to the e-mail address that you have used for purchasing the software.

There is no need to uninstall the trial version, just install the full version over the trial version, you settings will be preserved.

How do you search for a folder over a certain Number GBs and older than a certain date? I 'm trying to find data to archive off my file server

Please start the TreeSize File Search using the Tools or the Windows Start menu, Activate the Custom Search type only on the "Search Options" tab and adjust the search parameters on the "Custom Search" tab accordingly.

Is one user license sufficient if the software is installed on one computer though two or three users may access the software.

Basically you need as many licenses as you have PCs on which our software is available for execution. If these three users work on the same PC at different times, then one license is sufficient. If they work on three different PCs and start the software there, then you will need three licenses.

how can i schedule a job so that it can automatically deletes the files in a specific directory which are older than one year.

You can use the TreeSize File Search to schedule such a job. You can find a step by step description for this use case here.

Can TreeSize Professional sort and display files based on last accessed date?

Yes, you can sort TreeSize lists by any shown column by clicking on the header of the column. In case of the "Last Access " column, the list is sorted from the oldest to the newest date value. Click the header again to sort the list from the newest to the oldest. This behavior is equivalent to windows explorer.

The wasted space shown by TreeSize is extremely high. How can I reduce the wasted space?

Probably, you are using the FAT32 file system, which causes serious wasting of disk space becauseof it’s large block structure. Please read the chapter "Wasted space" in the manual, so will learn to understand and to tackle this problem.

How can I perform a "silent" installation ?

If you run the installation file and provide the parameters /SILENT and /PASSWORD=<YourInstallPasswordHere> on the command line, the software will perform an installation without any questions and just adhering to default values. Using /VERYSILENT instead of /SILENT prevents also a visual feedback. The option /DIR="X:\InstallPath" can be used to specify an alternative target directory for installation.

How can I set TreeSize to export one report with size information made in GB and another report with size information made in MB?

Please use the command line parameter /SIZEUNIT N to set the desired size unit in your exports. The parameter N is an integer value, denoting these settings:
0 = Bytes; 1 = KB; 2 = MB; 3 =GB.

If you don't use this option, size information will be made the same way, like it was done in the last export/report.

The sum of the sizes over the bars in the File Age tab differs from the total of used space. Is this caused by file compression?

The shown sizes refer to the used hard disk space as shown in the Directory Tree. These sizes indeed could be different, depending on compression and/or cluster size on the harddrive (see also the topic on Wasted Space in the product manual).

What is the difference between the Professional and the Personal Edition?

The Personal Edition has the same features as the Professional Edition, except that it cannot be used with Windows server operating systems, does not support scans of network shares which are part of a Windows domain, provides no command line options and no scheduled scans.


The Personal edition scans network drives if the computer it runs on is not part of a Windows domain and the remote system is not a Windows server. This enables customers of the Personal Edition to scan network drives in their home network, including NAS systems based on Linux and Samba.

Please find a comparison chart here.

Is there a way to set the depth level for the exported scan results in XML files like it is possible for Excel exports?

The XML files were meant to store the complete results of a scan for recalling them later and to compare them with the latest scan results. So there was (and is) no need for limiting the result display to a certain scan level.

If you are interested only in the uppermost level of the file system, CSV or Excel exports are quite comfortable, too.

If you simply want to reduce the total size of the XML file, you could deactivate the statistics on users and file types.
