The most effective C disk cleaning method

**Introduction:** If you're facing a full C drive, the Computer Knowledge Learning Network offers practical solutions to free up space on your Windows system. Start by using the software **SpaceSniffer** to analyze disk file usage and clean up unnecessary files. This tool provides a visual representation of what's taking up space, making it easier to identify and remove large or redundant files. **One: Disable or Adjust the Hibernation File (Hiberfil.sys)** The hibernation file, `Hiberfil.sys`, can take up several gigabytes of space. To disable it, open the Command Prompt as an administrator and type: `powercfg -h off` This will completely remove the hibernation file. If you prefer to keep hibernation enabled but reduce its size, use: `powercfg -h -size 70` This sets the hibernation file to 70% of the original size (typically around 2.8 GB for a 4 GB RAM system). **Two: Move the Virtual Memory File (Pagefile.sys)** The virtual memory file, `pagefile.sys`, can also consume significant space. You can move it to another drive by adjusting the virtual memory settings in System Properties. Go to **Control Panel > System > Advanced system settings > Performance Settings > Advanced > Virtual memory**, then change the location. **Three: Manage System Restore Points** The **System Volume Information** folder stores system restore points. To reduce its size, access Group Policy Editor (`gpedit.msc`) and navigate to: `Computer Configuration > Administrative Templates > System > System Restore` Disable the "Turn off System Restore" policy if needed. Additionally, under `Windows Components > Windows Installer`, disable the "Turn off the Create System Restore checkpoint" option. To delete the contents of the **System Volume Information** folder, run the following command in an elevated Command Prompt: `cacls C:\System Volume Information /e /g everyone:f` Then remove the folder using: `rd /s /q C:\System Volume Information` Note: This may require multiple attempts if permission issues occur. **Four: Clean Up the Winsxs Directory** The **Winsxs** folder contains Windows update files and can grow quite large. Use **DISM++** to clean it up. Open the software, select the "Scan" option, and then click "Clean" to remove unnecessary files. **Five: Remove RRbackups Folder** If you have a ThinkPad, the **RRbackups** folder is created by the Rescue and Recovery program. You can delete it through the Rescue and Recovery interface or by uninstalling the software. Alternatively, boot into Safe Mode, enable showing hidden files, and manually delete the folder. **Six: Enable Compact Mode (Windows 10)** Compact mode compresses system files to save space. However, it’s not recommended for mechanical hard drives due to potential fragmentation. To enable it, run the following command as an administrator: `compact /compactos:always` You can check the saved space by comparing disk usage before and after. To disable it later, use: `compact /compactos:never` **Conclusion:** By following these steps, you can significantly free up space on your C drive.
