Win10 system comes with compression function

Now we use the computer to use 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 system image
below to compact mode let's make a comparison, wim images were released to the Compact and normal mode, after the completion of the file to view the amount of space occupied as follows:

Compact mode (left) and normal mode (Right) release image files take up space
contrast can be seen, the original 7.29GB file, after compression 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. the amount.
Only Windows 10 supports Compact boot and supports both UEFI and BIOS.
The above is the introduction of Win10's own system compression function. Generally speaking, the system will have several Gs, so the space saved by this system compression function is also considerable.
