# Why does Collab Sync ask me to confirm a large folder?

Because mirroring a big folder copies all of it to the other Mac, Collab Sync makes sure you meant it. Its review shows the size and file count, and for a large folder you tick **This is a large folder (…). Sync it anyway.** before you can go on.

If that's more than you wanted, choose a smaller subfolder instead.
