How to use the Win10 system with its own compression function

Now we use the computer to save various files in the computer, so if the computer memory is small, there will often be insufficient disk space, which will hinder the use of our usual computer. . Why does it cause insufficient disk space on the computer? First, because our computer stores too many files and takes up space, another important reason is that the memory occupied by the system itself is too large, and a win7 and win10 system are occupied. Most of the space, so it will cause the space to be full. Now win10 has a new function, it comes with system compression function, you can compress the system files, reduce the occupation of memory by system files, which can greatly compress the space. Some friends with small computer memory can try this method.
Compact compression is somewhat similar to NTFS file compression, but Compact compression is higher, comparable to Wimboot, and it is said to use the same compression algorithm as wimboot.
If you are familiar with the way DISM deploys the operating system, you only need to add the /compact parameter to install the operating system in compact compression mode. For example:
DISM /Apply-Image /ImageFile:install.wim /Index:1 /ApplyDir:D: /compact

Application of system image in compact mode
Next we will make a comparison, respectively Release the wim image in Compact and normal mode. After viewing, check the file space usage as follows:

Compact mode (left) and normal mode (right) release image file space comparison
can be seen, the original 7.29 GB file, Compact compression saves about 2.6G space! Considering that there are many Windows tablets with only 32G storage space, and Windows is a large hard disk space consumption, if you use Compact mode to install the system will greatly reduce the storage space consumption. .
Only Windows 10 supports Compact boot and supports both UEFI and BIOS.
The above is the introduction of the use of Win10's own system compression function. Generally speaking, the system will have several Gs, so the space that this system compression function can save is also considerable.
