* SD.open() new feature for creating all folders in path This PR adds to the SD.open() function option to create all folders to the file. SD.open(const char* path, const char* mode, const bool create) Default value of create is false. When true folders are created. From issue #5019 * Update vfs_api.cpp memccpy -> memcpy * File f = open() edit added false for create
