Ultimate C Drive Cleanup Guide: From Beginner to Expert

Why Is Your C Drive Always Full?

As the system disk, C drive carries Windows OS, registry, system page files and other core data. Over time, three types of 'killers' gradually devour your space: 1. System junk: Old packages left by Windows updates (WinSxS), system temp files (Temp), error reports. 2. Software caches: Browser caches, WeChat/QQ chat logs, video software buffer files. 3. User habits: Default download path on C drive, all software default install on C drive, desktop full of large files. This guide will help you tackle these issues one by one.

Phase 1: Basic Cleanup (Safe & Risk-Free)

Suitable for all users, no technical knowledge needed, use built-in tools to free 5-10GB space.

1
Disk Cleanup Tool
Right-click C drive -> Properties -> Disk Cleanup -> Clean up system files. Check 'Windows Update Cleanup', 'Previous Windows installations', 'Temporary files'. Click OK to delete.
2
Enable Storage Sense
Settings -> System -> Storage -> Turn on 'Storage Sense'. Configure to run daily or weekly, automatically delete Recycle Bin files older than 30 days.
3
Clean WeChat/QQ Cache
Open PC WeChat -> Settings -> File Management -> Change File Storage Location. Change path from C:\Users\... to D:\WeChatFiles. WeChat will automatically migrate chat history.

Safety Warning

Do not directly delete files under C:\Windows, C:\Program Files and their subdirectories unless you know exactly what they are. Accidental deletion may cause system crash or software failure. Before operations, please use system's built-in 'Create Restore Point' function to backup current state.
