Files with these suffixes get a lower priority when multiple files match a wildcard. See |suffixes|. Commas can be used to separate the suffixes. Spaces after the comma are ignored. A dot is also seen as the start of a suffix. To avoid a dot or comma being recognized as a separator, precede it with a backslash (see |option-backslash| about including spaces and backslashes). See 'wildignore' for completely ignoring files. The use of |:set+=| and |:set-=| is preferred when adding or removing suffixes from the list. This avoids problems when a future version uses another default.
