What is a document library?

A document library provides a secure place to store files where you and your co-workers can find them easily, work on them together, and access them from any device at any time. For example, you can use a document library on a site in SharePoint to store all files related to a specific project or a specific client. Adding files or moving files between folders is as easy as dragging and dropping them from one location to another.

Note: Does your screen look different than this? Your administrator may have classic experience set on the document library. If so, see Introduction to libraries. If you're a document library owner, site owner, or administrator, see Switch the default experience for document libraries from new or classic for the steps to set the default experience.

Note: Some features are currently only available in classic experience. Click Return to classic SharePoint in the bottom, left corner of the page to switch to classic experience.

The default site in SharePoint and SharePoint Server 2019 includes a document library and one is created automatically when you create a new site. You can add additional document libraries to a site as needed. This is useful, for example, if you need to restrict access to a set of files. Each document library displays a list of files, folders, and key information about each, such as who created or last modified a file. You can use this information to organize your files and make it easier to find them.

In a document library, you can:

Add, edit, delete a file, folder, or link from a SharePoint document library, co-author, and download documents.
Control who has access to a library, a folder with in a library, or an individual file within a library.
Track the activity on a file, such as when it was last modified, and receive a notification when something has changed.
Create a custom view of a document library
Share files or folders with others.
Add a link in a document library to something that is stored outside the library, for example, a link to a file located in a different library or even a link to an external web page.
Highlight a link, file or folder in a document library so you and others can get to them quickly.

Let's take a look around
