Win10 system comes with compression function using tutorial

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

applications in compact mode image
Here let us make a comparison, respectively, Compact and release wim images to 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
we can see, 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.
