About clean and speed up computer

No matter your computer uses HDD or SSD, it will face the “insufficient disk space” problem, which plagues many users. When insufficient disk space, you need to free up disk space in time, especially the C drive. Because C drive full will make the computer run very slowly, or even crash.

How to clean and speed up my PC for free? If you search the answers on the internet, you will find that many forums will tell you to empty the recycle bin, delete unnecessary files, uninstall unnecessary programs, use Disk Cleanup to delete temporary files, or turn on Storage Sense, and so on.

Although these methods are easy and free, after trying these methods, you will find that they are not completely effective, and the disk still does not have much space to keep the computer running smoothly.

▶ Part 2. Defrag hard drive to make it run faster

Just cleaning up junk files is not enough, we also need to run disk defrag.

Disk Defragment

Repeated downloads and deletes create fragmented files, which make the disk take more time to read the data. Disk defrag can make the discontinuous data on the sector became continuous, which reduces the search time and improves the speed.

Due to the different structures of HDD and SSD, please do not perform disk defrag on SSD. Otherwise, it will affect its life.
If you want to improve the performance of SSD, you can try SSD 4K alignment.

Step 1. Install and launch AOMEI Partition Assistant Standard. Then, right-click on the target disk and select "Disk Defrag".
