The file created by Wireless Diagnostics ends with the .tar.gz extension, which indicates that it is a compressed archive file commonly used on Unix and Linux systems, but also applicable within macOS environments. When Wireless Diagnostics collects data, it packages the collected logs and diagnostic information into this format, making it easier to handle and share.

The .tar.gz format combines the functionalities of both a tarball (the .tar part) and gzip compression (the .gz part). It initially gathers multiple files into a single .tar file, and then compresses that file to reduce its size, which is particularly useful for sharing or archiving data effectively.

In contrast, the other file extensions mentioned serve different purposes. For example, a .zip file is a different type of compressed archive, .dmg is a disk image file utilized for software distribution in macOS, and .log indicates plain text files that typically store logs and are not compressed or archived. Thus, the specific use of .tar.gz by Wireless Diagnostics for organizing and compressing its output makes it the correct choice.
