How to transfer files to virtual OS on Hyper-V?

Question

Hyper-V

Good afternoon!
Needed a 32 bit system. I decided to put it on Hyper-V, but I never did it. In general, now I have a virtual Windows 7.
I don’t understand how you can transfer a file from 8 to 7. The clipboard can only transfer text. And I did not understand where the files of the virtual 7-ki are stored.
