When non-empty, overrides the file name used for |shada| (viminfo). When equal to "NONE" no shada file will be read or written. This option can be set with the |-i| command line flag. The |--clean| command line flag sets it to "NONE". This option cannot be set from a |modeline| or in the |sandbox|, for security reasons.
