In corporate environments, automated backup systems generate filenames based on timestamps, serial numbers, or database row IDs. A file like H-RJ01233190.rar could easily be a backup of a specific project folder, a legal document set (H perhaps standing for "Human Resources" or "Housing"), or a weekly archive that was inadvertently indexed by search engines.
The presence of "RJ" followed by a numerical string is a significant clue. In certain online communities—particularly those surrounding Japanese indie games (doujin soft), visual novels, or digital art—the code "RJ" is widely used as a cataloging system. H-RJ01233190.rar
