Can I convert multiple OLM files at once using a converter tool?

What advanced features should users expect in a modern OLM conversion tool that supports multiple file formats and email clients for efficient data migration and management, and can CloudXena OLM Converter provide functionalities such as duplicate email removal, date-based filtering, selective folder conversion, custom naming conventions, and attachment management while converting OLM files into formats like PST, MBOX, EML, MSG, PDF, and CSV, and how do these features improve the overall conversion process by allowing users to control what data is converted and how it is organized after migration to email clients like Gmail, Office 365, Yahoo Mail, and IMAP accounts, and are these options useful for users who need to handle large volumes of data while maintaining organization and efficiency, and does the tool also provide options for splitting large output files and managing storage effectively?
