I really like TreeSize Free, but I'm no big fan of the new ribbon interface, as it's just too large. Can I switch back to the old toolbar view?

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, perform the following steps:

  • 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

I scanned my mobile device with TreeSize Free, but the total size calculated differs from the occupied space the Windows Explorer shows.

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.

How can I change the language of TreeSize Free? After the installation, all menues are shown in german, but I would prefer them being in english.

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.

I have installed TreeSize Free from the Microsoft Store, how can I activate the context menu entry in the Windows Explorer?

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

If you want to use TreeSize Free from the Explorer's context menu, please use one of the other versions (Installer or Portable), which offer this option.

Why does TreeSize Free show different size values than Windows Explorer?

These differences can occur because the free version does not take all NTFS-specific features into account.The personal and professional edition come with an option to analyze NTFS features like hardlinks and alternate data streams, which may make the results more accurate.

Am I allowed to use TreeSize Free in a corporate environment?

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.

Do you offer a portable version of TreeSize Free?

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.

Can I use TreeSize Free to scan my mobile phone?

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.

Does TreeSize Free support scanning network drives?

Yes, scanning network drives is fully supported by the free version, unless the network share lies within a Windows domain. This is mostly the case in larger environments, such as a company network. The professional edition also supports scans in Windows domains.
