Have you ever found yourself in any of the following situations?
You want to apply the same Meta data to all items in a folder.
You were advised to use SharePoint Views to organize your SharePoint List items instead of folders and you are looking for a way to cascade Meta data to some items in your SharePoint list.
After migrating Items in to a SharePoint folder, you realize that you need to apply a consistent meta data to better identify them.
If any of the above is YES, then the meta data editor is for you!!!!
