About the Create a GZIP File

GZIP compresses one stream. It has no concept of file names or folders, which is why the Unix world pairs it with TAR - the TAR holds the structure, the GZIP compresses the result.

It is also the compression used for web responses, which is why measuring the gzipped size of a JavaScript bundle is more meaningful than measuring the raw size.
