Compression will happen on-the-fly and the files can be accessed transparently as they were before compressing. Windows 10 supports NTFS compression natively like previous versions of Windows.

This is because of extra operations the OS has to perform when the file is accessed, copied out of a compressed folder or put inside a new compressed folder. During these operations, Windows has to decompress the file in memory. As it follows from the name of the feature, NTFS compression doesn't work when you copy your compressed files over the network, so the OS has to decompress them first and transfer them uncompressed.
