1. Delete temporary files. In Windows system, many programs will generate temporary files when they are used, and these files may not be deleted automatically, which takes up a lot of space. You can choose "temporary files" in the disk cleaning tool to clean it, or you can enter "%temp%" in the run box to open the temporary folder of the system and delete all the files in it.
2. Clean up the recycle bin. When deleting files, many people forget to empty the recycle bin, resulting in the space occupied by deleted files still being reserved, occupying a lot of space on disk C. You can right-click the recycle bin icon and select "Empty the recycle bin" to clean it.
3. Disable the hibernation function. In Windows system, the hibernation function can make the computer enter a low power consumption state when not in use, saving power, but the hibernation function will occupy a certain space on the C drive. You can find "Power Options" in the Control Panel, and select "Never" in "Change Computer Sleep Time" to disable the hibernation function.
4. Uninstall unnecessary programs. In the process of constantly using computers, we may install some programs that are not commonly used, and these programs will take up a lot of space. You can find the "uninstall software" option in the control panel to uninstall unnecessary programs.
5. Clean up the browser cache. When browsing a web page with a browser, the browser will automatically cache some web page data, which will occupy the space of drive C. You can find "Clear Cache" or "Delete Browsing History" in the browser settings to clean it up.
In short, the cleaning of disk C is a continuous process, and you can choose the appropriate method to clean it according to your own needs and habits. Cleaning can not only make more space for other files, but also make the system run more smoothly.
