OneDrive is free online storage that comes with your Microsoft account. You can Save files there and you can get files from any PC, Tablet, or Phone.
To save a doc you’re working on to OneDrive, select a OneDrive folder from the list of save locations. To move files to OneDrive, open File Explorer and then drag them into a OneDrive folder. See picture in below.
Files you save to OneDrive are available online at OneDrive.com and offline on your PC. That means you can use them anytime, even when you’re not connected to the Network. When you reconnect, OneDrive updates the online versions with changes you made offline. Offline files come in handy when you’re stuck without Wi-Fi.
File Explorer icons show you the sync status of your offline folders and files.
