If both of the drives have the same data and syncs correctly then it is mainly because of the issue with the Windows 10 and its upgrade. This also is the reason for different data because some apps might still be set to store data in the older folder. Since the SkyDrive and OneDrive names are different, your system treats them differently and hence the 2 separate folders. If your drive was named SkyDrive in your previous Windows then upgrading to Windows 10 (where it is named OneDrive) causes this issue. The problem basically occurs because of the Windows upgrade and drive name.

The problem of having two instances (or folders) showing in Windows Explorer only seems to be a cosmetic issue but it sometimes it isn’t. Sometimes you might see not one but two instances of OneDrive in your Windows Explorer especially if you recently upgraded to Windows 10 from Windows 8. There’s no doubt that there are many benefits of using OneDrive but sometimes you might face a few issues that are quite troublesome especially if you have important stuff stored on the cloud. Microsoft’s OneDrive also provide a great way of syncing your clout storage for access from multiple devices. OneDrive is Microsoft’s cloud storage platform that lets you store your important documents and media files on the cloud.
