StExBar Alternatives
StExBar is described as 'The StExBar provides many useful commands for your everyday use of Windows explorer. And you can add as many custom commands on your own as you like' and is an app in the file management category. There are three alternatives to StExBar for Windows and Windows Explorer. The best alternative is FlashFolder, which is both free and Open Source. Other great apps like StExBar are FileBox eXtender and Explorer Breadcrumbs.
FlashFolder is an open source tool that extends the file-related common dialogs (e.g. open/save dialog) seen in most Windows applications. A small toolbar docks onto these dialogs that provides menus for quick access to recently-used folders, favorite folders and more.
Discontinued
Only inofficial versions for Win7 up ... buggy and no support from Zett42, developer that seems to be out of office. So pls mark as discontinued - average user will have too many problems.
FileBox enhances Windows by adding several advanced functions to the standard Open File and Save File dialog boxes. (Note that if a program uses its own "private" dialog boxes for these functions, you wont see our FileBox buttons, sorry.)
Discontinued
FileBox eXtender is no longer supported. The binary builds and source code are available for download.
Explorer Breadcrumbs is an add-in for Windows Explorer which contains a contextual series of buttons that allows you to quickly see and navigate through the entire folder hierarchy without leaving the current window.
Discontinued
Last version, 1.3.0.1, was released on 2007-04-08. It can be still downloaded from Wayback Machine.
