When you copy or move a compressed NTFS file to a different folder, NTFS decompresses the file, copies or moves the file to the new location, and then recompresses the file.Compressed files are also expanded before copying over the network, so NTFS compression does not save network bandwidth.Files or folders saved into an existing compressed folder will automatically be compressed.If you disable NTFS file compression, any currently compressed files will still remain compressed.
