What GZ and 7Z files are
GZ
GZ is a gzip-compressed file using the DEFLATE algorithm. It compresses a single data stream, which is why it usually wraps a TAR archive (.tar.gz) when bundling many files on Unix systems.
7Z
7Z is a high-compression archive format created by the 7-Zip project. It uses the LZMA and LZMA2 algorithms to achieve significantly better compression ratios than ZIP or RAR.
