In SharePoint 2013 you can easily create or modify views for lists and
libraries by simple filtering or sorting in the current view. I have created a
team site which has Documents library. I have uploaded few documents in
the document library. This document library has “All Documents” as
default view. I have sorted the documents based on Name in descending
order. Now you can find an option called “SAVE THIS VIEW” next to the
search button as shown in the following figure
Click on SAVE THIS VIEW.
You can click on Save button to save the changes to the current view or
you can change the name of the view so that a new view will be created as shown
in the following figure
