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?

The HTTP spec says nothing about directory indexes.

Generating indexes is up to the application running the HTTP protocol, it could very well serve a recursive TAR of the directory if the administrator wanted that.
