I found the following bug on WinMe (I call it a bug, since the behavior is
different on WinMe than for instance Sun Solaris):

When calling file.exists() with an existing directory name ending with a "/"
(slash) [R] on WinMe will return FALSE, but when doing the same without the
ending "/" it will give TRUE.

I made a quick work around, but this should be taken care of in the native

file.exists <- function(...) {
  # Remove trailing "/", but keep "C:/", "D:/"...
  files <- gsub("\:/$", "\://", c(...));
  files <- gsub("/$", "", files);
