Ninja is a free tool for maintaining and cleaning Windows from unnecessary files, a perfect complement to the popular CCleaner. During its operation, the program scans the contents of the hard drive for files that can be deleted in order to recover the disk space occupied by them and improve the overall performance of the system - among other things, to reduce the time it takes to run the application and the system itself. One of its main advantages is its high efficiency in detecting unnecessary data, and also, as the author ensures zero probability of deleting important system files.

The Ninja system works better than CCleaner in many cases, detecting components that can also be removed without fear. In its area of activity you can find such components as temporary files created by applications and the system during installation or operation, Internet Explorer history, thumbnail buffers (Thumbs.db), unsupported icons, Windows logs, various types of logs, Torrent tags, which occur in the form of small text files and many others. Clearing your system from unnecessary files is not the only application of the Ninja System.

It also includes additional tools for managing applications running with Windows and planned tasks (Startup Manager) and processes (Process Manager). The latter, unlike the system mechanism of the Task Manager, is able to close many positions at once, and also detect malicious processes, responsible for viruses, trojans, etc., which is why it is so important to use the system. In addition, the Ninja System offers a number of simple but interesting features, such as cleaning only selected folders, generating a report with a list of applications running with the system, and an analyzer that provides detailed information about the files (location, size, creation and modification date) and allows you to create checksums (MD5, SHA1, SHA256).
