Saladin

Saladin is a dual-panel open-source file manager that combines the features of Window Explorer with an orthodox user interface that's comfortable, intuitive, and easy to use.

The dual-panel interface makes it much easier to work with files. You'll be able to do everything much faster as well since all the icons and menus for accessing files are fully integrated. You can move files from one panel to the other as needed just by dragging and dropping.

Whenever you copy or move a file, a confirmation message will appear so you don't accidentally change the names of any of them in the process. Another integrated feature lets you search for files by name or by content and edit them directly from within the search results.

Saladin allows you to zoom and rotate pictures with its image viewer and adjust the size of the window if they're too big. It's also compatible with ZIP files, which you can browse just like in an ordinary directory.

Finally, it's compatible with basic FTP connections so you can connect with an FTP server via Window's integrated client. This lets you upload and download files as well as carry out other basic operations.
