gz
gz is different from tar.gz, you will fail to extract files if you use tar for gz archive. The compress ratio are low, this is an old ways of compress file, seldom see people doing that anymore. The different between tar.gz and gz besides compress ratio, is when you create a gz, your source file will be compressed into gz (source file will be missing), then same thing happen to decompress gz, after decompress, gz file is missing.

Awkward archives
Sometimes I do obtain certain zip file contain tar.gz and vice versa, therefore you need to decompress another time after you extract the tar.gz out from zip file. It is kind of rare, but it does exist.
