How do I unmount a disk drive?

To unmount a volume:

1. Open Disk Management. From your Start menu, choose Windows Administrative Tools, then Computer Management. Then, under Storage, choose Disk Management.
2. Or, press Win + X (hold down the Windows Key and press X), and choose Disk Management.

Can internal storage be removed?

So you should be able to free up some storage space by deleting these unnecessary files. You’ll find your downloads folder — which might be called My Files — in your app drawer. Tap and hold a file to select it, then tap the trash can icon, the remove button or the delete button to get rid of it.
