I use Ubuntu Studio 20.04.2 LTS inside a 64 bit machine.
I also use VirtualBox 6.1 which I used to create a Windows XP SP3 virtual machine.
But, when I get in that virtual machine (WinXP), I cannot to read or write any from the Ubuntu mounted HDD partitions. I'm specially concern about the My documents folder (music, images, videos, etc.), because the WinXP virtual machine doesn't see that folder or HDD.
What I did wrong?
How can I get to read and write into the Ubuntu My documents folder when I am into the WinXP virtual machine?
