You spend the whole week working on some code and then take the weekend off. Get in on Monday, compile, then realise that it's actually a bit of a mess. It's easier to go back to the previous code, from the start of the week, rather than debug. You'll need to go through the old (working) code and the new (buggy) code, side by side, to see the differences between the two.
WinMerge 2.6 is a free tool that enables you to load a document and then compare it against another. This is ideal for coders as you can quickly see the differences between your old and updated code. You can then make necessary changes or merge some of the old work in to the new document.
If you're a web developer or a programmer, download WinMerge 2.6 and see how it compares to your existing tools.
