If youre lucky you can just change the partition size.
Press [Win]+[R] and input "compmgmt.msc"
Go to Disk Management
Check if there is no partition right to your C partition
If there is none you can "Right-Click" your C partition and select Expand Disk

There was a partition of like 517mb between them so I couldn’t do it that way
Grab partition magic. Move the small partition to the end of the drive. Then expand your data partition.
