SharePoint 2013 - Change URL of document library - SharePoint Stack Exchange: "When you create a document library, it ask you the name for the DL. Once you give it, it will create library with same name and URL. You can change the name of the library any time but cannot change the url. Here are the things i followed to create url accroding to my needs:
Just go to a library trough 'Site Content'
When inside the library choose on the ribbon 'Library' tab.
Then select 'Open with Explorer'.That will open your SharePoint's library in Windows Explorer window.
Navigate one folder up and you will see list of your libraries as folders.
Rename required library's folder name as you want the URL to look like.
Close the windows and refresh the browser or go back to home page and browse the library again.
