Multi Commander is a free file explorer for Windows that is packed with features. I found it while looking for a dual pane Commander clone to use instead of Windows Explorer. Listed below are some usage tips and shortcuts I use regularly:
Quick Look n Feel Setup: The first time you start it, it allows you to choose between a setup like Commander or like Windows Explorer. No matter what you choose, you can customize everything to your liking later. The startup dialog can be accessed later through Configuration -> Quick Look n Feel Setup. Note that if pick either choice in this dialog, it messes up all your customizations, so I would recommend not touching this dialog at all.
Fonts: Fonts used for UI elements in the presentation area (where your files are listed) can be changed in Configuration -> Explorer Panel Settings -> Display Tab -> Fonts. Fonts used for the tabs can be changed in Configuration -> Core Settings -> Layout tab -> Application Layout -> Panel Tab.
Colors: Colors used for every single UI element are configurable! Find the Colors tab in both the Configuration -> Core Settings and Configuration -> Explorer Panel Settings.
Show file extension: Enable it under Configuration -> Explorer Panel Settings -> Display Tab -> File and Folder Display -> View Mode Settings.
Open new tab:
Ctrl + T
Close current tab:
Ctrl + W
Path field: The current path shown at top is not editable by default. Double-click on the empty space to its right to make it editable and copyable. This can also be done by pressing
Ctrl + E. The path of the currently chosen file can be copied by pressing
Ctrl + P.
Favorites: These can be accessed by clicking the ⭐ icon in the Command Line Bar at the top. The same dialog can be invoked by pressing
Ctrl + Backspace. In this dialog, you can add and order paths under Quick Paths and Favorites. Quick Paths can be launched using shortcuts like
Ctrl + 1,
Ctrl + 2 and so on.
Button Panel: The button panel at the bottom can be toggled using
Ctrl + B. I just keep it toggled off at all times.
Tried with: Multi Commander x64 v9.7 and Windows 10 x64
