Your new drive will be accessible by clicking on My Computer or the icon on the taskbar next to your clock.
From there you'll be able to drag and drop any file or folder and have it instantly uploaded or synced to your OpenDrive account. You can Open, Modify, and Save files just like a traditional drive, but you can also right click on the file or folder and under Properties you'll find the link to share file with anyone.
Your files will be remotely accessible from any computer by visiting OpenDrive.com and signing in with your username and password.
