A list of file patterns. A file that matches with one of these patterns is ignored when expanding wildcards, completing file or directory names, and influences the result of expand(), glob() and globpath() unless a flag is passed to disable this. The pattern is used like with :autocmd, see autocmd-patterns. Also see 'suffixes'. Example:

:set wildignore=*.o,*.obj

The use of :set+= and :set-= is preferred when adding or removing a pattern from the list. This avoids problems when a future version uses another default.
