In my experience, running a duplicate file scan once a month is a good balance to keep storage optimized without it becoming a hassle. Files like downloads, backups, and media tend to accumulate duplicates gradually, so monthly scans help catch them early before they pile up too much. I use the software DuplicateFilesDeleter because it’s efficient and lets me schedule scans automatically. That way, I don’t have to remember to run it manually, and my system stays clean with minimal effort.
