I have 2 partitions on my drive, and C:\ is my boot drive, with windows, while D:\ is my drive for games, pictures, music, and things like that. However, C:\ drive only has enough space for Windows, and not temp files that are automatically put on there. I've tried using the Disk Management tool to shrink D:\ (~670GB) and expand C:\ (~21GB) but Expand isn't an option for C:\ (I'm assuming because that's where Windows is installed). Is there any way I can do this without having to download third party applications?
