This document compares the use of folders versus metadata for organizing documents in SharePoint. It explains that metadata involves assigning attributes or tags to describe documents, while folders act as containers. Using site columns to define metadata attributes provides more flexibility than folders for filtering, sorting, tagging multiple attributes per document, and reusing definitions across libraries. However, folders still have advantages for security, large file volumes, and avoiding file name collisions. The conclusion recommends planning a taxonomy first using reusable site columns for metadata before relying solely on folders.
