If you want to enlarge C with Disk Management,
1. Save everything from D to an external drive.
2. Then right click on D and delete the volume to get unallocated space.
3. Right click on C and extend it to at least 50GB
4. Right click on the remaining unallocated space and define a new D partition
5. Move the saved data back to D
That is the easiest way to do it. Else you will need another program like Partition Wizard. But even then I would first backup the data on D for safety reasons.Agree +1 :)Regardless what you do, backup your data from D first. Last time I used PW, I lost 3 whole partitions - it was, of course, my fault. But it is easy to make a mistake. Fortunatey I had an image of everything.
I still think it would be easier for you to use Disk Management as described above.
