Win10 system reduces the hard disk space occupation trick

To be fair, the Win10 system footprint is not too high. Even so, there are still many people who want to free up more space for other files by compressing the Win10 system. This is also very simple, as long as you use Compact compression technology, you can achieve it, let's take a look.

1. Run CMD as an administrator and enter the following command to enter.

compact /compactos:always

As you can see, it saves about 2.0GB of space after compression. Take a look at the actual hard disk space usage comparison:
The picture on the left is before compression, the picture on the right is after compression

2. If you want to turn off after turning on Compact, just execute the following command:

Compact /compactos:never

It should be noted that Compact does not affect system performance, but it may produce disk fragments that are difficult to organize. It is not recommended for use on mechanical hard disks.

The above measures to reduce the hard disk space of the Win10 system, if your system is installed on a solid state drive, you can use this method to save valuable SSD space.
