I was wondering how you can make a shared folder between your VM and your actual PC, so that when you make a printscreen on your VM you can access it on your PC

Thank you in advance

Do this with a shared clipboard rather than a shared folder. If the clipboard is set to "Guest to Host" or "Bidirectional" then the PrtScr key will copy to the clipboard as usual, and you can paste it to the host.

Shared folders are for files.

Alternatively (if you don't want to enable shared clipboard), then paste the image from the guest clipboard into a guest paint program, just like you would do on the host. Then save the image anywhere you like.
