NTFS compression function can compress the entire directory tree on a single file, the entire folder or NTFS volume, which can help us save some hard disk space. However, using the compression function will cause the performance of the NTFS volume to drop. The reason is that each time you access the compressed file, you need to decompress it.

Therefore, it is recommended to try not to use the compression function when the hard disk space is large enough.
