One of my partitions are full, can I use some space from other partitions to extend this one?

I have three partitions on a terabyte hard drive, and they're all split up into fairly equal sizes for different uses. One of them is now full thanks to the only two games I own eating away at my hard drive as if gigabytes grow on trees.

Is it possible to extend this partition by shrinking the others? Is it hassle-free, and can I do it with the Disk Management tool? Will any of my data on any of these three partitions be corrupted in any way? I'm on Windows 10.

also sidenote question: if i compress folders that are quite sensitive (adobe suite work), is it safe to delete the original folder? or should i store it somewhere else and keep the compressed one too?

ok thanks guys

i meant is instead of are but it's too late now
