I’m working with a large ICS file containing thousands of calendar events, and managing the entire file has become difficult. Opening, sharing, or importing such a large calendar file can also take considerable time. I’m looking for a reliable way to split the oversized ICS file into smaller parts without affecting the event details or calendar structure. I came across SysTools ICS Splitter, which appears to provide options for dividing large ICS files into smaller, manageable files. Has anyone used it for handling large calendar files, and how well does it preserve the original event data?
