We are using a SharePoint by creating individual document libraries dedicated to specific jobs. Each of these document libraries has roughly the same folder structure having the same base folder structure, i.e. 01 Documents, 02 Photos, etc.. As out processes evolved we have seen the necessity to rename some of the base folders. I don't see any clear way to automate going into each library, finding the specific folder(s) to rename (which are known), and renaming the folders. How could this be accomplished as we have many existing libraries. Similarly, would the same process be used to add any new, missing base folders that we are creating to older libraries?
