How can I split a large ICS file into separate event-based ICS files?

[keth charles]

I have one massive ICS file containing hundreds of events, and it’s nearly impossible to manage or share selectively. I need a way to split the ICS into smaller files—either by event, date range, or calendar category. I found SysTools ICS Splitter, which seems useful because it lets you divide ICS files into multiple smaller ones without losing any metadata. It also keeps the original structure intact and handles bulk files pretty smoothly. Has anyone tried it?

You can split a large ICS file by exporting each event into its own ICS, and the easiest way is using SysTools ICS Splitter. It automatically breaks massive ICS files into smaller, event-based or date-based files while preserving all metadata, attachments, and formatting. The tool supports bulk processing, keeps the original folder structure intact, and avoids corruption issues common with manual methods. If you need clean, organized, shareable ICS files without hassle, this utility is a reliable, time-saving option.
