I may have already written a post on Revo; I can’t remember. I just had to stress the awesomeness that is Revo.
What Revo does is, when you pick a program, runs it’s built in uninstaller then searches your hard drive for any leftover files. Today, when I was uninstalling Arora, Revo found 1,951 files left over in my Application Data folder. 1,951. That’s just… incredible.
It also has an excellent Hunter Mode and some other great tools; check it out. I seriously recommend it to anyone.
