The Store Version only opens a message dialog.
Unfortunately it was necessary to create a separate project in the Microsoft Store for the latest version of TreeSize Free.
The version in the legacy project is only a dummy version of TreeSize Free, which does not provide any functionality anymore, is not updated and only serves as a reference to the new version.
If you want to continue using TreeSize Free and get all updates, please uninstall the old version and switch to the new version here.
Please excuse the inconvenience.
