AB Commander is a tool that lets you manage your files and folders using the convenient dual-panel user interface (pioneered in Norton Commander), while maintaining close integration with the standard Windows shell. AB Commander has the following features: The main window of AB Commander hosts two panels, independently displaying the contents of folders of your computer, just like the built-in Windows Explorer does. Each panel may be used to browse all folders, both virtual and real ones, located on local or remote drives. Powerful means of navigation between folders: the Favorites lists, the History lists, the pop-up Folder Tree window that lets you browse the whole hierarchy of folders; the drive bar and drive list. Commands to directly manipulate files and folders (copy, move, rename, delete). Built-in file splitter lets you split large files into smaller segments and then merge them back with ease. Various ways of customizing the look and feel of the listings shown in the panels according to your preferences: single- or double-click activation, full row selection, underlining the hot or cold items. Command prompt lets you quickly run programs that accept command-line arguments.
