Combine files with explicit exact-duplicate and revision handling.

Opening your local workspace…

How it works.

  1. 01Choose calendars and inspect merge diagnostics.
  2. 02Review exact duplicates, UID revisions and ambiguous conflicts separately.
  3. 03Apply explicit choices and export the merged result.

The important details.

Newer SEQUENCE and revision timestamps inform decisions. Fuzzy matches are suggestions, never automatic deletions.

A good question.

Are similar titles automatically removed?

No. Similar-looking events can be legitimate; fuzzy matches require your deliberate choice.

Keep going.
