If a path name ends in slash then file.exists says it does not exist.
I would have expected these to all return TRUE.
file.exists("/Program Files")
[1] TRUE
file.exists("/Program Files/")
[1] FALSE
file.exists(normalizePath("/Program Files/"))
[1] FALSE

I am using Windows 8.1 .
See ?file.exists:
"(However, directory names must not include a trailing backslash or

Note also that "/Program Files" is not safe anyway since it is relative
to the current drive.
