Lotus Notes 8.5 spills hundreds of megabytes of files in the root directory of either the boot volume or the volume which is the destination of the Notes install, (and usually these are one and the same). Imagine if all software developers made a practice of doing this. It's outrageous and not done by IBM on the Windows platform.

I know OS X has lower market share, but if you bother to develop for this platform, do it right. IBM, clean up this mess you carelessly make in the root level. Leave root alone.
