What's the difference between this program and the freeware CCleaner? The developer should create a comparison chart between TweakRam and freeware versions of this software otherwise why purchase.
But these all "RAM cleaners" work the same way - they put the content of the RAM into a swap file, "freeing" some space. But when the swapped content is needed, it takes more time to load because HDD is slower than RAM. SO this software is completely useless. I'd rather buy a new RAM module.
Why compare with CCleaner? Because CC is a really useful software doing what's it's supposed to - removing junk files without trying to do useless things.
