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 Office 365 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 mode 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 for document libraries from new or classic for the steps to set the default experience.

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

The default site in Office 365 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, 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

At the top left of the document library page is the main menu.

Here you can create a new folder, document, or a link to something that is located outside the document library,

Office 365 Create a new folder or document

or upload a folder or files.

Office 365 Upload files or folder to a document library

You can also sync files in the document library to your computer or create an alert to receive a notification when something has changed.

At the top right of the document library page, you can change the document library view to either list view or grid view. If using Internet Explorer, you can open the document library in Windows File Explorer, by clicking View in File Explorer. You can also save a custom view by clicking Save view or, if you are a library owner or administrator, you can manage views on the library settings page by clicking Manage views.

You can add new columns and select the columns to display by clicking Document Library Add a Column Button

on the far right side of the column headers if you're in list view or, if you're in grid view, by clicking Document Library Arrange Button

and then clicking Document Library Add a Column Button

on the far right side of the column headers.

Create a custom view of a document library

You can view and edit information about a file or folder, such as required properties, recent activity or who a file is shared with, in the information pane. To show or hide the information pane, select a file or folder and click Document Library Details Pane

on the right-hand side of the main menu. You can also view the information pane by right-clicking a file or folder and selecting Details.

When you select a folder or file, the menu at the top left of the document library changes to a list of actions you can perform on that folder or file.

NOTE: To expose the file or folder menu when in thumbnail view, click the top right corner of the thumbnail.

You can see another version of the document menu by right-clicking the file name or, if in list view, by clicking Office 365 Document library list ellipses
