You can create folders and subfolders in a document library to organize your files into categories that make sense for your business. For example, you can create folders to store the files for each client or for files related to a specific project. Moving files into your folders is as easy as dragging and dropping them into the appropriate folder. You can also control access to or share a folder or a single file within a folder.
Go to the location in the document library where you want to create a new folder.
On the menu bar, click New and then click Folder.
Note: Does your screen look different than this? Your administrator may have Classic Mode set on the document library. If so, see Add a folder to a library for the steps to perform this task.
In the Folder dialog box, type a folder name in the Folder Name box and then click Create.
When done, you should see your new folder in the document library and can start adding files or creating subfolders within it. To add a new file, see Create a new file in a document library. To upload existing files, see Upload a folder or files to a document library.
If you don't see your new folder in the list, refresh your browser.
