Systems, methods, and data structures for providing a file system with object versioning support are provided. Rather than adding object records for each version of an object to a chapter record, in one example, the chapter record may be limited to a single object record for the object including: (i) an object name of the object; (ii) an object file handle identifying an index of a file containing data of a current version of the multiple versions of the object; and (iii) a version table file handle identifying an index of a file containing a version table. In this manner, enumeration of objects associated with a given chapter may be performed more efficiently and prior versions of objects may be maintained within the version table without disproportionate growth of chapter records and without increasing the search depth with objects that are not referenced by the search at issue.
