how to merge drive c and d

Sometimes computers have two drive partitions for factory install of software or the computer was set-up that way by mistake. It is not uncommon for our users to run into this issue with Windows 10. Especially if they had previously upgraded from Windows 8.1 or an earlier version.  It is also possible your computer has two separate physical drives. In that case the steps below won’t work. If however your drive is one physical drive that is partitioned into multiple this should do the trick. BEFORE you do this you will want to back-up any data that you may need from D: first.

    3. Open the File Explorer and right-click on “This PC,” then navigate to Manage → Computer Management → Storage → Disk Management.
