Introduction

StackOverflow is an amazing site for coding questions.

If you're like me, you constantly move and rename files and directories. You are also an extremely productive person with evangelical ideals of making every task as efficient as it can be. In this tutorial, I will use my favorite must-have file manager called Total Commander (formerly, Windows Commander) and its brilliant Multi-Rename Tool.

You can download a shareware version of Total Commander at www.ghisler.com. I encourage you to buy it after you try it as it'll soon become an integral part of your life. I've been using it for more than 10 years now and seriously can't imagine my computer without it.
