System Ninja is a tool that comes in handy when you want to get rid of unnecessary files from your system, in order to free up space.

The interface of the application is simple and quite intuitive. You can select the types of junk files you want System Ninja to look for, and initiate the scanning process.

So, you can clean the temporary, incompatible, thumbnail and recent files, common torrent tags, thumbnail, game and Internet cache, memory dumps, Internet cookies and history, Windows logs, and others.

Furthermore, you can scan the entire hard drive or just a folder of your preference. In the list you can check out the path, size and type of each file.

Once the system scanning is complete, you can delete a file, ignore it or all of its type, open the containing folder and save results to a log file.

Furthermore, you can access the "System Tools" tab to remove programs which automatically run at system startup, terminate currently running processes and analyze files (e.g. MD5 checksum). But you can also view system information in "PC analysis" regarding your hard drives, processor, logical disks, motherboard, BIOS and operating system.

In "Options" you can create an exclusion list, change the interface language, enable to preserve the window and column sizes, as well as  disable System Ninja from checking for updates automatically, displaying a warning before files are deleted, and more.

The application requires a moderate amount of system resources, can guide you to an online help section and didn't freeze or crash during our tests. Unfortunately, there is no option to select or deselect all files. Otherwise, we strongly recommend System Ninja to all users.
