ExtractNow

If you've ever had multiple archived files and you were extracting them one by one, then you know the painfulness of your index finger on the mouse.

Look no further than ExtractNow. This isn't the end-all-be-all archive utility. In fact, the only thing it was made to do is to extract multiple files at once without the danger of sequential clicking.

So if you have lots of archives, and you need to take those and extract them all at once... then you've hit the jackpot. Freeware for Windows.
