Explorer is no different to other Windows applications in the way it includes toolbar that can be used to quickly access common options. As you are browsing through your files you will notice that depending on the type of folder you have selected, there are buttons on display that can be used to do everything from burning files to disc or adding them to a playlist to emailing them or changing sharing properties.
Explorer Toolbar Editor is a free tool that can be used to customise the buttons that are displayed in the toolbar - and it is possible to choose which buttons should be visible depending on which folder or library is selected. You can opt to apply the same toolbar to all folders and libraries, or you can take your customisation a step further and opt to use a different set of buttons for different types of folder or library.
The utility is handy for anyone who wants to streamline the Windows interface. If you find that your windows are cluttered up with buttons you never use, you can use the application to eliminate anything you do not need - should things change in the future, you can always revert back to the default settings.
Similarly, you may well be perfectly happy with the default selection of buttons that Microsoft has decided to include in the Explorer toolbar, but this does not necessarily man that you agree with the order in which they have been displayed. Using Explorer Toolbar Editor, you can easily change the order of toolbar buttons as well as adding and removing them so that Explorer can be perfectly tailored to suit the way you work.
