Win10 comes with system compression function

Win10 system comes with a system compression function called Compact. This compression function does not compress ordinary files, but can compress system files to save space. Win10 comes with system compression function is very convenient to use, let's take a look at it.

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
Applying a system image in compact mode

Let's do it again In contrast, the wim image is released in Compact and normal mode respectively. After viewing, the file space usage is as follows:
Compact mode (left) and normal mode (right) release image file space comparison

To, 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 install the system in Compact mode, the storage space will be greatly reduced.

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.
