# note: cygdrive has been remapped to /drv at my place Good gracious! (btw, thank you for the explanation) - 'e:\' is a DOS path - e:/ is not a DOS path (removing the trailing /, yields e:) However, ls -ld e:/ refers to /drv/e (e:/ is interpreted as 'e:\' by ls!) So do rmdir, stat, touch ... (and many other commands) They are all wrong ... Correct? How about e:/foo ????? A DOS path? Does it refer to /drv/e/foo? According to https://cygwin.com/cygwin-ug-net/using.html#pathnames-win32 it is a DOS path (and NOT foo in subdirectory e:) Said differently, e: is a subdirectory, and e:/ is the same thing, because a trailing forward slash is ignored (like Linux does).
