With cloud storage you can store your files in a centralized location and be able to access, share, and edit the files from anywhere.
Common cloud file storage service providers are Dropbox, Google Drive, Box, and Microsoft OneDrive.
Many cloud based file storage services operate by setting a particular area of your hard drive as being the cloud based drives. Anything you put in this folder will be synchronized to the cloud with a synchronization application. If you have the synchronization application on another device, the files will also auto synchronize on the other devices as well.
