> +Modification 2 :+
> [https://github.com/apache/carbondata/blob/master/docs/file-structure-of-carbondata.md]
> Since Metadata folder contain segment, tablestatus and schema folder so  dictionary file related content inside metadata folder can be removed from doc.
> eg : Metadata directory stores schema files, tablestatus and *dictionary files (including .dict, .dictmeta and .sortindex).* There are three types of metadata data information files.
