+The f_chdir function changes the current directory of the logical drive. Also the current drive is changed at Unix style volume ID, FF_STR_VOLUME_ID == 2. The current directory of each logical drive is initialized to the root directory on mount.
+Note that the current directory is retained in the each file system object and the current drive is retained in a static variable, so that it also affects other tasks that use the file functions.
+Available when FF_FS_RPATH >= 1.
