The Keyboard-Oriented File & Folder Explorer for Efficiency, or Koffee, is a no-nonsense alternative to Windows Explorer focused on VIM-style keyboard shortcuts, speed, and simplicity. It is built on .NET WPF, written in F#.
Why would I want to use this?
The goal of this application is to allow users to navigate and manipulate files and folders very quickly, almost at the speed of thought -- a speed only achievable via keyboard. If you've ever experienced the productivity boost that comes from learning and using all the keyboard shortcuts in an application (or learned to use the text editor VIM), you understand what a big difference it makes.
Koffee depends on Microsoft .NET Framework 4.5.1. You may already have it installed; look for it in the list of installed programs in "Programs and Features" (Windows 10, 8, 7, or Vista) or "Add or Remove Programs" (Windows XP). If you don't see it, head to Microsoft's download page to download and install it.
To install Koffee, go to the releases page. From there, you can download and run Koffee-Setup.exe, which will guide you through the installation with a wizard. Or, if you prefer to install it yourself, you can download the zip file, unzip the app wherever you want and create your own shortcuts.
First of all, take your hand off of the mouse because this is a keyboard tool! Once you're familiar with the hotkeys, you'll be navigating your files more quickly than you ever could with a mouse. If you're familiar with the text editor VIM which is popular among programmers, you should feel at home.
Capitalized letters indicate that the key is combined with Shift.
