ICS Splitter Tool to Divide Large Calendar Files

Split ICS calendar files into smaller iCalendar files with preview, folder selection, split methods, and optional date range filtering. Create cleaner calendar sets for review or sharing.


Features of ICS Splitter Tool

SysCurve ICS Splitter Tool divides large or mixed calendar files into smaller ICS output files by item, count, month, or year. Preview records, apply optional date range filtering, and create new calendar files without overwriting the source data.


Split ICS files by practical methods

Choose one file per calendar item, a fixed number of items per file, split by month, or split by year. These options cover common calendar cleanup, archive, and sharing needs.

Preview events before splitting

Review the selected calendar entries before output is created. This helps confirm the file contains the expected meetings, tasks, locations, dates, and descriptions.

Use date range filtering for focused files

Create split output only for the selected period when a full calendar export is too broad. This is useful for quarterly archives, annual folders, and project timelines.

Process selected files or folders

Add individual ICS files or select a folder that contains several calendar exports. The same split settings can be applied across the selected file set.

Create new ICS output files safely

The software writes new ICS files in the destination folder based on the chosen split mode. Original calendar exports stay unchanged.

Generate an optional split log

A processing log can show selected files, split mode, date range settings, skipped items, and output details after a larger job.

Make large calendars easier to handle

Smaller output files are easier to import, share, store, and review than one broad calendar export containing too many records.

Keep the work local on Windows

The split process runs on your Windows computer and does not require a live calendar account connection.

More capabilities

Useful extra controls for calendar review, batch work, and output setup.

Split modesItem, count, month, or year.
