The problem with Windows is that it's continually creating temporary files and leaving them behind. This can seriously slow down your system over a long period of time. This utility is suited for systems that contain too many unused files that have been created over a PC's lifetime. In other words, it does a pretty damn thorough search of every last remaining unnecessary file.
Sometimes such data can be well hidden or buried within your operating system but Dustbin deep searches your entire hard drive until it finds files that have literally been there since you first got your computer. For such a deep search however, the scan is suspiciously short taking only a few minutes depending on the size if your drive. However, it's very low on resources and is often updated so that it requires minimal CPU usage and maximum performance according to the developers.
A very fast deep scan that might not do everything it says on the tin but will still throw up a few surprise files you never knew existed.
Search speed improved

Very simple to use
Can be executed from the command prompt
Doesn't remove everything that it claims to be able to
This utility is suited for systems that contain too many unused files, created during a system lifetime and have now been left behind. This data might be secret and hard to find or you might not have enough time or experience to do it manually.
The utility is smart and fast, find ten megabytes per few seconds although everything depends on your system, how many files do you have on your disk, how many devices you have on your board etc.
