Downloaded a .gz and Windows won't open it?

Linux-world downloads repacked as ZIPs: the tarball inside is understood, unpacked and rebuilt.

Downloads from the open-source world arrive as .gz files, usually a compressed tarball, and Windows meets them with a shrug. Conversion here understands the layering: the gzip is decompressed, a tar found inside is unpacked, and everything rebuilds as one ordinary ZIP with folders intact. A bare gzipped file without a tar simply becomes a ZIP holding that file. Either way the result double-clicks open, and the processing never leaves your browser.

Questions

What is actually inside a .gz download?

Usually a tar bundle that was then gzip-compressed, which is why plain unzipping tools get confused. Both layers are handled here.

What if my .gz holds a single file, not a tar?

It becomes a ZIP containing that file, still double-clickable.

Uploaded anywhere?

No, the layers unpack in-browser.
