This software combines multiple features such as file shredder, disk cleaner, privacy eraser, free space wiper, and startup editor. It can securely erase files, find junk files, erase activity tracks and recent documents, clear cache and cookies, wipe free space, and manage startup programs.

The file shredder module is a powerful tool that permanently deletes files from the hard disk. It uses secure algorithms compliant with the US Department of Defense 5220.22 M sanitizing standard to ensure that the deleted files cannot be recovered or "undeleted" with disk recovery tools. The File shredder module is integrated with the Windows shell, which allows users to erase files from any windows-compatible file manager, such as Windows Explorer, using a context-menu.
The privacy eraser module removes user activity tracks and other unnecessary data from the system, protecting user privacy. It contains various eraser tools, such as an IE address box typed URLs eraser, Recent Documents folder eraser, temporary (temp) folders cleaner, internet history eraser, web browser's cache eraser, IE forms auto-complete cleaner, open/save dialog history eraser, FireFox cache cleaner and many more.
The Junk file finder scans the drives for unwanted useless and temporary files left behind by various applications. This module helps users free disk space and optimize system performance.
The startup manager module allows users to control the Windows startup programs. It enables users to review the list of software that starts automatically during the system boot and delete unnecessary items.
The free space eraser module ensures that the hard drive's free space is genuinely free by erasing the drive's free space. Since deleted files are only marked as deleted, they occupy some space, which may result in a shortage of free space. Erasing the drive's free space ensures that this data cannot be recovered.
Overall, Jitbit System Purifier is an excellent software suite that provides an extensive set of tools to optimize system performance and protect user privacy. The user-friendly interface and easy-to-use modules make it an ideal software suite for beginners and advanced users.
