Doing file compares can be quite confusing using Compare-Object, so unless you only want to check for equality, using a GUI can be tremendously helpful. Enter WinMerge. I guess most of you have used, or are currently using, this fabulous tool. I created a simple wrapper for WinMerge so that it’s easier than ever to open file (or folder) comparison right from the PowerShell console.
The function is quite simple, and the help text should be enough to get you started. Please give it a try, and let me know what you think of it in the comments section below.
