Why is .lzh format still popular with japs?

The rest of the world uses .zip and .rar and these retards still seem to use .lzh a lot.

It's not because the format itself was constructed by a "fellow" Jap is it?

WinRAR is not such a PITA. The average user would still benefit from the trouble of installing it which isn't hard anyways. Why? Because of the beautiful thing called the right click. I can right click ANY archive and select "extract here" or "extract to folder" and BLAM! It's done!

Another beauty of winRAR, newer versions of it have at least rudimentary support for every major archival format. I can unzip .zip and .7z files with it.

.7z format is probably the best format I've seen for distributing various versions of the same thing.

I downloaded Final Fantasy 3 for SNES and the .7z file was about the same size as a single rom. (4.8MB) Inside the package however, was EVERY VERSION OF THE ROM RELEASED. This file contained 258MB worth of roms. Each only a little different than the others. Raring up just 2 of these roms had me with a file that was 4.2MB. You cannot honestly tell me that .7z isn't superior especially for things like this.

The best part of this? I was able to right-click the folder and go Extract to Final Fantasy III/ and all of the files were in that directory with nothing more than WinRAR installed.
