Welcome to the forums, newcomer!
FYI, each drive is allocated at least 10% of the drives capacity for Recycle Bin. That %age was for Windows 7. For Windows 10, each drive has it's own recycle bin allocation meaning you can't just throw C drive's recycle bin allocation over to another drive. You can right click on Recycle Bin, on your desktop, then go to Properties and you'll see the allocation for each drive.
