The Libraries feature was introduced in Windows 7 as part of the updated Explorer application. It allows you to consolidate multiple folders under a single Library so that content across various locations can be aggregated in a single folder-like view. The default libraries created in Windows are intended to group similar content like Pictures, Videos, Music and Documents. For example, the two Pictures folders - the one for your user account and the Public (Shared) pictures folder - are both included in the Pictures Library. You can add your own folders to any custom or predefined library. By default, Windows shows folders inside a library in the order in which you added those folders. You might be interested in reorganizing them and change their display order. It is a very simple, but not so obvious feature of Libraries. In this article, we will see how to re-order folders inside any Windows library.
