ToFileName

ToFileName["directory", "name"] assembles a full file name from a directory name and a file name.

ToFileName[, , ... , name] assembles a full file name from a hierarchy of directory names.

ToFileName[, , ... ] assembles a single directory name from a hierarchy of directory names.

ToFileName works differently on different computer systems.

ToFileName just creates a file name; it does not actually search for the file specified.

ToFileName["", "name"] gives "name".
