A new useful suite from Digeus: System Optimizer. It is a pack of applications (Disk Space Analyzer, Duplicate Files Finder, Junk Files Cleaner, Memory Cleaner etc. - a really huge list) provides the smartest way to solve computer problems and protect your valuable data. Sure, many of the applications exist in the free forms, but the well assembled pack of working utilities worth own money. It is definitely easy to use.
