The option to integrate with the Explorer's context menu is deactivated for the portable version and TreeSize Free would thus not create any entry.

If you want to use a portable version of TreeSize Free and still create context menu entries, you may create an empty file "unins000.dat" inside the folder where the TreeSize Free portable exe is located. Afterwards the option can be activated in TreeSize Free.

Please be aware that the context menu entries created this way are not being updated or removed if the program folder changes. Such context menu entries may thus become orphaned and should be removed beforehand.

The easiest way to remove the entries again is to deactivate the option on the 'Options' tab.

The official installer for TreeSize Free (as well as the portable version and the version available in the Windows Store) would not install any other applicationand and is tested to contain no malware, adware, or similar.

Please assure to download TreeSize Free from trusted sources only, like our official download server at https://www.jam-software.com/treesize_free

Should you believe you have found a conspicuous download source, please let us know.

Yes, there is:

On the 'Options' tab, click and expand the 'Options' drop down. The first entry of the now shown list ('Tooltips') allows you to chose between the available hint types:

- Only for cut off labels: Only shows a hint, if the content of a cell had to be cropped
- Show Long Tooltips: Shows a hint containing detailed information on an element
- Show a preview of the current folder's content: Shows a preview window on the current folder

With V4.1.1, the default option for the tooltips has been adjusted, so the folder content preview has to be activated manually.
The 'Tooltips' option has been moved to the 'Options' tab also, so it may be accessed more easily.

Yes, you can.

If it's just for the height of the ribbon menu, you may first try to minimize it. Just right-click on the menu and select 'Minimize the Ribbon'.
Using the right-click menu, you may also add commands to a quick access bar and create a toolbar specialized for your own needs.

To disable the ribbon interface completely you may use the command line parameter /UseRibbonUI false since v4.0.2:

  • Close TreeSize Free
  • Open the prompt to run a program (shortcut: Win + R)
  • Type in the path to TreeSizeFree.exe and the required parameter. This usually results in (including the quotation marks): "C:\Program Files (x86)\JAM Software\TreeSize Free\TreeSizeFree.exe" /UseRibbonUI false
  • With a click on 'Ok' you may now TreeSizeFree without the ribbon interface. This setting is persisted and will be used again at the next start of TreeSizeFree, so you would have to run this command only once.

As an alternative (which works for older versions too), you may change the setting in the GlobalOptions file:

  • Close TreeSize Free
  • Locate the file "GlobalOptions.xml" and open it with a texteditor at your choice (like notepad.exe).
    • When you used the default installer to deploy TreeSize Free, the GlobalOptions.xml should be located at %appdata%\JAM Software\TreeSize Free
    • For the portable version, the options file will reside in the same folder as the executable
  • Search for the text "<UseRibbonUI>True</UseRibbonUI>" and replace it with "<UseRibbonUI>False</UseRibbonUI>"
  • Save the file and close the editor. TreeSize Free will now start without the ribbon interface

To activate the ribbon interface again, please follow the same steps, but replace False with True (e.g. /UseRibbonUI true)

TreeSize Free can only see files the device exposes via the MTP protocol. Most likely, the missing space is occupied by the operating systems or other critical data and may not be accessed this way.

You may change the language at the beginning of the installation. Just select 'English' from the drop-down menu.

Or you may simply delete the file 'TreeSizeFree.DE', located right beneath the executable in the installation folder.

Apps from the Microsoft Store are executed in a sandbox and can not write to all of the registry. Creating a context menu entry from within TreeSize Free itself is thus not possible.

You can activate the context menu entries manually though. Please find the required entries for the Windows registry at TreeSizeFree_Context_StoreApp_Enable.reg

After downloading the registry file, you may just execute it to show the store version of TreeSize Free in the context menu of the Windows Explorer.

To exclude TreeSize Free from the Windows Explorer's context menu, please download and run TreeSizeFree_Context_Disable.bat.

Yes, you may use the free version in a corporate environment. However, scanning of network shares within Windows domains, as it is often the case in corporate environments, is only possible with the professional version.

Yes, our download page allows you to select either the .exe setup file, which can be used for a full installation, or a .zip file that contains the TreeSize Free executable, which can be run without installation.

Yes, TreeSize Free can scan mobile devices that are connected to the PC via USB. Most smartphones and digital cameras use the MTP (Media transfer protocol), which is not supported by many disk space managers. TreeSize, on the other hand, is able to scan these devices and show the disk space that is occupied on your mobile device.
