ExtractArchive can be used to extract files from an archive file, and returns the names of the files and directories it created.
ExtractArchive supports a variety of file formats, including ZIP, TAR, GZIP, BZIP2, 7z, RAR and ISO.
In ExtractArchive[source,…], source can be any of the following:
File["file"] or "file" file name, searched for on $Path

By default, ExtractArchive saves the extracted content in the current working directory given by Directory[].
