Is there a way to combine multiple ICS calendar files into a single ICS file?

[kethcharles]

I have several ICS files from different calendars and want to consolidate them into one file for easier management and migration. I’m looking for a solution that can merge multiple ICS files in bulk while keeping the existing events, recurring appointments, attendees, and other calendar details intact. I found SysTools ICS Merger Tool, which can combine multiple ICS files into a single calendar file. Has anyone used it for merging large numbers of ICS files before importing them into Outlook, Google Calendar, or Apple Calendar?
