Why does the pdf documentation come with cryptic names "inst_oes_lx" when they could just spell it out "install_oes_on_linux"

Why did someone think it was a good idea to had a single file in a directory of the same name "\inst_oes_lx\inst_oes_lx.pdf"

Why do they put in such information as "Be sure to complete the instructions found in the xyz" but don't include a link to xyz or even bother to tell you where to find it.

Just some questions
