I am always amazed 7zip hasn't supplanted WinRar and the Rar format.

This is because, on Windows, you can't double click a 7z file and have it open 7zip. If they fixed that, they'd have a winner.

If you have .7z files associated with 7z File Manager, it will open on double click. Is that not the default on installation?

It is the default. It's always worked for me just fine.

RAR has some unique built-in characteristics like recovery record (useful when archiving on optical discs, or any other media which can degrade in time) and recovery volumes (which was a life-saver feature in the age of floppy disks).

Another major contributor is likely that with rar you can make a multi-file self-extractor. Seem to recall that before broadband and torrents, many a pirated game was released as a split rar .exe that could fit on floppies and was spread across numerous upload sites. Dump them all in a dir, run the exe, and game on...

I believe winzip had the same feature of creating a exe zip spanning over multiple files, for using on floppies.

But the scene releases are not using 7zip to create the rars, are they?

Among the movers and shakers in the scene, isn't there generally a predilection to use free software over non-free software? E.g. the only time I run across matroska contained movies is when it's released from the scene.

Not really. There's a general predilection for the best software available, especially since they're unconstrained by purchase costs. Often the free program is the best, but not always.

Just what I was going to ask about. I thought WinRAR had the option to include parity checks / redundancy within the data.

BTW, is there a current... "turnkey" (simple, "clicky"), I guess, *NIX solution for doing that within an archive?

"Best software" - Are you joking? Scene releases use winrar mostly for packing and splitting. Usually null-compression is used.

There is this par2cmdline[1] tool which is (as the name suggests) a console program "for creating and using PAR2[2] files to detect damage in data files and repair them if necessary". GPar2[3] (alpha) is a simple GTK+ GUI for it.
