In a unixoid OS the users home directory is where apps store files. Where path-/filenames starting with a dot (".") in "home" are special and such pathnames are often used as "application pathes". All other pathes may need a special user to create/modify files.

By the way: os.getenv("USER") and os.getenv("HOME") seems to deliver nothing with Poser-Python (at least in my installation).
