SharePoint’s SiteManager is a great tool to manipulate folders and files; however, it can sometimes fall short at times when a massive amount files need to be relocated. With proper permissions, you can get around this by using Windows Explorer instead. PLEASE NOTE: When moving a mass of files around in this manner, you can lose certain file details — such as history data.
Moving Files in SharePoint Via Windows Explorer:
1. Open up your SharePoint page in internet explorer and copy the path (ie, http://dime/sites/yoursite).
2. Open up windows explorer and navigate to your web folders.
3. Right click on ‘Web Folders’ and select ‘New’.
4. Enter your path from step 1 and, like magic, you can drag and drop your files! 😀
