Serato DJ Pro guides
Practical, step-by-step guides for keeping your Serato library clean, fast, and gig-ready. Everything here is written for Serato DJ Pro on macOS and tested against a real library, not a fresh install.
New here? Start with the full Serato library cleanup routine, which ties every guide below together in the right order. If something is broken right now, jump to a corrupt database or missing files. If the library works but has grown messy, start with duplicates and crate structure. The five sections below run roughly in that order: repair first, then cleanup, then the habits that keep it clean.
