How can I redirect disk requests to RAM?

Question

Windows

Good day.
Let's say program A (or a set of programs) constantly writes something to a file or directory. Is it possible to make sure that nothing is actually written to the disk, while being invisible to the program, i.e. make the software work with virtual files in RAM? At the same time, the software itself cannot be touched; should work with any file and any disk access.
In other words, you need to intercept any disk access and redirect them to RAM.
Is there software that allows you to do this? OS Windows 8.1
Thank you in advance.
