I just downloaded TreeSize Free and am most impressed with how much you have built into the free version of your software. It is clearly a well engineered and carefully thought out product that will be very useful for finding clutter on my hard drive. It contains far more value than I expected, and I compliment you on a product well done.

I was using Treesize to manage the space on my drive after having installed the Android devkit, which resulted in my system downloading about half-a-dozen versions of the SDK, along with about six thousand version of Java!! Absolute bloomin' chaos.

Thanks for Treesize. I haven't had to use it for about a decade, but it's good to know it's still around, and works as wonderfully well as it every did.
