What is FileCoordination?

FileCoordination is a system process that stops file conflicts on your Mac.

What is FileCoordination?

FileCoordination manages the NSFileCoordinator system, the way macOS controls file access between several processes at once. When two apps try to use the same file at the same time, FileCoordination makes sure they do not wreck each other's changes.

Why is file coordination needed?

Without it, problems crop up:

• Two apps editing the same file could overwrite each other's changes
• An app reading a file while another writes to it could get broken data
• Moving or deleting a file while another app has it open could cause crashes

FileCoordination manages a queue of file access requests, making sure reads and writes happen safely.

What uses it?

• iCloud Drive (keeping local edits and sync in step)
• Document-based apps (TextEdit, Pages, Numbers)
• Finder (file operations on documents other apps have open)
• Any app using NSDocument or NSFileCoordinator

Does it use many resources?

No. It manages access coordination details, not the file data itself. The overhead is tiny.

Should you worry?

No. It is a normal macOS system process that prevents data loss when several apps use the same files.
