The OneDrive Sync Client.
This guide explains the purpose of Onedrive and how to set yours up, if it isn't already.
OneDrive is the replacement to the previous N drives, and should be used for personal storage to allow you to take advantage of the same sharing, file history and web browser based access that you’ll be able to use with the SharePoint Document Library. The OneDrive Sync Client is the program that maintains your local version of the SharePoint and OneDrive document libraries. It should start automatically at login, however as with any program, problems can occur. If you don’t see the Cloud icon in your system tray 
you can start it manually from the start menu/search box by searching ‘Onedrive’ in the Windows start bar and opening it.
This icon will also show the status of the sync so you know if there are problems, and will popup with information about sync issues such as file clashes. Details can be found in the link in the previous section.
The OneDrive app should already be installed on your college computer.
You should see it in your System Tray at the bottom right (down by the clock) when it’s running. If you haven’t logged into it, it will look like this.

Follow the sign-in steps using your College account.
