Excellent and reliable tool for MANY years and across many versions of Windows. Some ease of use in configuration would be nice but it's not required. Otherwise, I've used and beta tested hundreds of software products and this is one of those few products that filter past all other worthy tools and become permanent keepers. It does what it's supposed to do, without making too much noise or wasting my time and it does it extremely well! I have to feel bad for some of the people who've sadly written negative remarks.. well due to your laziness in figuring out your own problems and blaming it on the tool, or just simply not reading the documentation, or not asking others for help, or just having unrealistic expectations, or some other senseless reason you're now having to live with the consequence of using a lesser quality competing product.
design looks like the program was written in 1974 or so. poor GUI, lots of command-line tools... this is 2015. when only 1 file needs defragmenting starting from the contect menu, the c: disk is analyzed. why ? even a 3 kb plain text file starts a >30 seconds defragmentation process !? uninstalled.
