Do you ever want to do any of the following tasks?

• View two Word documents side-by-side so you can compare them or more content between them.
• View two Finder windows side-by-side so you can move files from one folder to another
• Make a window fill your entire screen

If so, Cinch ($7) is an easy to use application that lets you accomplish these tasks. I regularly need to file documents that have accumulated either in my Downloads folder or on my Desktop into a folder elsewhere on my Mac. In order to do this easily, I’ll open two Finder windows, then move them to one of the edges of my screen which triggers Cinch to automatically resizes them to fill half of my screen. With the two windows sitting side-by-side, I can easily file my documents. If my description isn’t sufficient, please check out the brief but excellent video demonstration.

You can download Cinch from the Irradiated Software web site and try it for free. Irradiated Software also makes a slightly fancier window management utility named SizeUp ($13) that lets you accomplish the same tasks using keyboard shortcuts, along with additional features.
