TreeSize can scan Linux/Unix servers using the SSH protocol (see "Scan Targets"). Alternatively, if Samba is installed and running on the Linux/Unix system, our tools can access a share on this system using its UNC name, e.g. \\ComputerName\ShareName.

If the file system on the Linux/Unix system is accessible through NFS, then it can be accessed if the NFS support for Windows is installed. For Windows 7 and higher (Professional / Enterprise Edition), please go to the Control Panel and activate the "Services for NFS" under "Programs and Features > Turn Windows Features on or off".
Then you can mount an NFS share to a drive letter using this command:
mount \\ComputerName\ShareName N:

It might be necessary to create the following registry values if you have trouble connecting the NFS drive:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default\AnonymousUidas DWORD with the decimal value 10011.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ClientForNFS\CurrentVersion\Default\AnonymousGidas DWORD with the decimal value 10012.

Generally, you still need to be within your maintenance period to be able to update the product. If you are not, you can reactivate or extend it at any time.

The easiest way is to use the "Check for update" button on the "Help" ribbon bar within the program. The program then checks for the latest available version and installs it.

It is also possible to download the installer for the latest version of TreeSize from our customer area. The login details for our customer area have been emailed to you after the purchase and are printed on the license document. To upgrade older versions, simply run the installation file, the old version does not need to be deleted before. Your user settings will still be preserved during the upgrade.

To activate the full version, you only need to enter your personal license key in the application. To do this, start the application and select “Enter license key” under “Help”. You can find your license key in the license document in the e-mail that you received from us after your purchase, or alternatively in our customer area.

Please note: If your test period has already expired, a dialog will appear automatically when you start the application, in which you can enter your license key.

The evaluation copy allows you to test the software before you buy it. The maximum time to do this is 30 days. Further usage of the software after this period is not permitted and violates the law. In order to allow our customers to fully test our software products, the evaluation copy does not contain functional limitations, except: In the File Search the "Delete/Move/Archive" operation processes only a certain amount of checked files per execution, and the software may remind you from time to time that you should purchase the software after your testing is finished.

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.
