system disk full?
- The space reserved for the system disk is too little when partitioning.
- installed too many software, and the default path was selected when installing the software. As a result, the software installation file occupies the system disk.
- installed some synchronization tools, but did not save the settings to other paths. They will be synchronized to the default system disk, such as Baidu network disk.
- Some software will generate a large number of recording files, but the software does not set the path to other disks, which causes the default system disk to take up a lot of space. For example, QQ, WeChat, etc.
- After some software is installed, some dependent files will be installed on the system disk, occupying a large amount of system disk. Such as AUTOCAD, 3DMAX, Visual Studio, etc. The virtual memory drive of the system set by
- is C drive, which will take up a lot of system disk space.
How to expand the system disk?
Our traditional cleanup is too troublesome. Let’s change our thinking. If other disks have extra space to borrow and use, that’s the killer feature of the system disk that we’re talking about today—disks. Expansion.

My current system disk capacity is 60G, I want to change it to 80G. The method is to see if the drive letter has extra space and I will move it over.
I found that my D drive has a lot of space left, so I can borrow it. Right-click the D drive-adjust/move the partition
I want to borrow 20G to the C drive, and drag the circle directly to adjust it. This is more intuitive.
After clicking confirm,There will be an extra 20G drive letter, this is the D drive free for you,
Next, we merge the 20G space into the C drive, right-click the extra 20G empty drive— —Merge partition
Select the C drive (system disk) you want to merge — click OK
After confirming that the capacity of our drive letter is the size we want to change, Click Submit.

Open our explorer and see that the C drive (system drive) has become about 80G of space. So far, the borrowing of space is successful.
