Golden Match: One-stop cleaning of C drive

Software performance acceleration will inevitably increase the size of the software itself, as well as the cache and various temporary files.

Usually, we use a solid-state drive as the system disk, also known as the C drive. Assuming a 500GB solid-state drive, we allocate 200GB for the C drive and 300GB for the D drive.

Some computers have smaller C drives, so it is common for the C drive to run out of space.

I'm sharing a set of C drive slimming solutions that I use in my daily life, hoping it will be helpful to you.



This is a standalone version of Kingsoft junk cleaner, without any advertising plugins or residue. It cleans the system junk thoroughly and quickly. I have been using this tool for many years and I don't have to worry about it deleting anything it shouldn't. It gives me peace of mind.

Usually run once a week.



A well-known system cleaning tool, I remember it used to focus on erasing all internet traces. It mainly focuses on browsers and the registry, so use it with caution.

It clears junk files that are no longer used by the Windows system to free up more hard disk space. Another major feature is clearing the user's internet browsing history. It can clean junk from folders, history, recycle bin, and can scan and clean junk items from the registry. It supports Simplified Chinese.

After running this software, you will need to log in again to your browser accounts and refresh icons such as bookmarks. From another perspective, if you plan to use your office computer for personal matters, running this software will clear all your browser-related records, thus protecting your personal privacy.

Usually run once every one or two months.


IObit Smart Defrag

This is an intelligent disk defragmentation tool that uses the most advanced disk fragment intelligent diagnosis technology in the industry to quickly analyze, organize, and optimize disk performance. It supports defragmenting system files such as page files, hibernation files, MFT tables, registries, and specified files.

It can clean up fragment junk that cannot be removed by cleaning tools, and its dashboard UI design is very beautiful.

Usually run once every three months.



If after using the above junk cleaning and disk defragmentation tools, there is no significant increase in the capacity of the C drive, you should consider whether there are large-sized software installed on the C drive, such as Adobe series, 3D rendering software, etc.

TreeSizeFree is an open-source and free hard disk space management tool that provides a tree-like description, displaying file sizes, actual space occupied, wasted space, and other information, allowing you to make appropriate deletion decisions. However, this decision is not easy to make, so friends who are not familiar with computer systems should use this tool with caution.

If you don't allow easy deletion, then what is its use? It allows you to know which software is occupying the capacity of the C drive, so you can decide what to do next.

  1. Uninstall software that was installed but is no longer used.
  2. For software that must be kept, can it be moved? For example, Adobe software can be moved to another drive using the FreeMove tool mentioned later.
  3. If there is no software that can be moved and junk has been cleaned up, and the capacity of the C drive is still too small, what should you do?
    1. If the solid-state drive is divided into C and D drives, then allocate excess capacity from the D drive to the C drive.
    2. Buy a larger capacity solid-state drive on Singles' Day. If it can be solved with money, then don't bother.

Use as needed.



A simple and easy-to-use system software uninstallation tool, the free version is sufficient. After uninstalling software, it also cleans up the corresponding registry entries. However, I must remind everyone to be careful when deleting registry entries!

For example, uninstalling version 2023 of Photoshop and deleting the corresponding registry entries will affect other versions, such as Photoshop 2018, and reset the user settings of the software.

Use instead of the system uninstallation tool.



Its main function is to seamlessly move installed programs to other partitions.

Free up space on the C drive by moving software installed on the C drive to, for example, the D drive. This is equivalent to leaving a shadow on the C drive, while the actual entity is on another drive. It's like the effect of Monkey King's hair.

The operation is clear at a glance, just test it with an unimportant software to understand it.

Use when needed.



If the capacity of your system disk is small not because the hard disk is not large enough, but because it was initially allocated too small?

No problem, use a free partition assistant, for example, allocate the excess space on the D drive to the C drive. The operation is simple. After completing the allocation, click submit and restart the computer once. This capacity allocation is not a reinstallation and has no impact on the system or software. It simply transfers the excess space to the partition.

Alright, the C drive is resurrected!



There are many tools for slimming the C drive, but no single tool can do everything. Cleaning system junk, defragmenting disks, uninstalling unused software, moving large files, expanding partitions.

Each tool has different features and targets different areas of the C drive. If a doctor relies solely on one prescription to treat patients, they are either a quack or a fraud.

Regardless of how many software tools are used, our goal is to slim down the C drive. However, if your system disk is only 100GB, no matter how you rearrange and move things, it will not be enough. It's best to solve the problem fundamentally by spending a little less on cigarettes and buying a larger solid-state drive.
