Yes indeed: the Dos* functions call truename to convert the user-provided pathname to a "fully-qualified" name in the SDA (DOS data). This name has no . or .., always has a drive letter, and is always uppercased (except for UNC pathnames \\SHARE\... which don't have a drive letter). The dos_* functions in fatfs.c expect such canonical pathnames, just like the redirector functions (INT2F/11xx, used by *CDEX, network file systems, etc.) do.
