Creating a large folder hierarchy in SharePoint Document Library using Microsoft’s standard GUI takes a lot of time&#151which is unnecessary. Here’s an easier way:

1. Create the folder hierachy first on the hard disk.
2. In Internet Explorer, select Open from File Menu.
3. Provide just the link of the document library?for example, http://servername/DocLibName, without incuding allitems.aspx.
4. Check Open for the Web Folder option and press OK.
5. Then, simply paste the folders!
