Today, I’d like to recommend a C: drive cleanup tool: LightC. It’s designed to remove junk files, caches, and update patches that have accumulated over time, helping to alleviate low disk space and lag on your C: drive. Designed for everyday computer maintenance and office use, it’s compact, features a focused cleanup process, and is ad-free.
Core Features
- Scan various types of junk files—such as system temporary files, memory dumps, installation packages, and software caches—with a single click.
- Assign a safety clearance level to each type of trash, allowing users to decide for themselves whether to delete it, thereby preventing the accidental deletion of important files.
- Average users can usually free up more than ten GB of space.
- Built-in large file cleanup and disk space analysis, sorted by file size, with an intuitive display of the space occupied by large files and compressed archives
- A dedicated social media cache-cleaning module designed for image and video caches in WeChat and QQ
- Clears only the image and video cache; does not delete chat history, protecting your privacy and data integrity.
- You can disable the Windows hibernation feature to free up disk space equal to the amount of RAM.
- Clean up uninstallation leftovers and repair the registry to keep the system clean
- Automatically backs up before each cleanup; data can be restored if an error occurs
