(This is an OS-level difference: Windows is not POSIX compliant.) See also the manuals, e.g. http://cran.r-project.org/doc/manuals/r-release/R-exts.html#Operating-system-access and FAQs, e.g. http://cran.r-project.org/bin/windows/base/rw-FAQ.html#What-should-I-expect-to-behave-differently-from-the-Unix-version This was really a question for R-help, not R-devel.
