How to free space on the system disk in Windows 10 using the Compact OS

The volume of modern hard drives reached such quantities that for space-saving can be forgotten forever. However, many users are using laptops or tablets equipped with solid state drives. Their size may be small, so each gigabyte in this case the account.

Operating System Windows 10, depending on the version, the disc takes from 15 to 20 GB. If the memory capacity is only 64 or 128 GB for the user programs and files remain practically nothing. In that case, there is a built-in utility Compact OS, by which the operating system takes place can be slightly reduced.

Compact OS removes all the excess that is not required for operation of Windows, including image recovery. The remaining system files and applications are subject to universal compression algorithm using 4K XPRESS Huffman. As a result, the disk may appear about 6 GB of additional space.

If you too want to free up some extra space, follow these steps.

Open a terminal Windows as an administrator and type the following command, with which you can check the current status of the disc:

compact / compactos: query

It may be that the system has already been compressed. Do not be surprised, Windows is able to self-activate this feature when space is limited.

The second option - "The system is in a state of compression, but if necessary, can go into it." In this case, enter the following command:

compact.exe / CompactOS: always

Run the utility Compact OS and start data compression. Depending on the drive speed and the number of system files, this process may take different times. By its end, you will see a summary with the number of compressed files and compression ratio.

Please note that in some cases the system compression can lead to loss of productivity. This is due to the fact that now for each access to the files they will decompress on the fly, it can take some time.

Probably no slowing down you will not notice, especially if you have established a sufficient amount of RAM and has a solid state drive with a good data reading speed. You should not only include the system disk encryption (BitLocker feature), as this will cause extra strain on the processor and disk and accurately will reduce the speed of Windows.
