GZIP is a file format is a data compression format widely used for file archiving and for transporting data compression on the Internet.

The Import command can automatically uncompress gzip archives and attempt to parse the underlying data.

The FileTools[Compressed] package provides tools for reading from and writing to gzip archives.
