Microsoft OneDrive is a cloud-based service that creates a folder that automatically backs up everything between your computers and OneDrive.com.
When installed, you can get to your files from virtually anywhere. Whenever you add, change, or delete files in one location, all the other locations will be updated.
If you forgot to put something in your folder, you could still get back to your PC to access its files and folders from the website.
Microsoft OneDrive lets you access it right from Windows Explorer to easily find your photos, documents, and all your other important files. You can quickly add new files to Microsoft OneDrive by dragging them to the main folder.
