ntfs compression files and folder

[Ashish]

To compress a file or folder right click and go to property and select
compression. Ntfs also allows to compress whole drive.
What this compression means? does it compress file contents?

NTFS keeps collection of MFT records for all files and folder which we call
meta data. Does compression work on MFT record also?
If we compress a file or whole drive then will it compress the MFT record
also.
