Best Practices
For libraries that contain a mix of document types, organize the documents by how they are used.
For libraries that contain only one type of document, include a template for creating new documents, and create separate libraries for each template you use.
WSS limits searches to the site level. If you're not using MOSS or MOSS/S, include all of the libraries you want members to be able to search in top-level sites rather than subsites.
Use folders (physical organization) when migrating files from network drives to SharePoint. Folders provide the easiest migration path.
Use views (logical organization) when your library serves a wide audience with varying needs. Views give you the greatest flexibility.
Before uploading large groups of files, check for these characters in file or folder names: &, ?, %, or .. (two periods together). SharePoint can't accept files or folders with those characters in their names.
Use default column values to populate document properties when uploading files in bulk.
Use the datasheet view to quickly change property settings after uploading files in bulk.
When creating libraries that use versioning, be sure to explain your revision process to users who will be working with those libraries. Depending on how the library is set up, they may need to know how to check files in and out, how minor and major revisions work, and that documents may require approval.
