1. Edit the settings of Ubuntu virtual machine.
2. Go to storage and add Ubuntu iso file. (for example ubuntu-20.04.1-desktop-amd64.iso)
3. Start the virtual machine and boot from CD by pressing F12 and then press C

Once Ubuntu starts open Files. You should be able to access your files now.

You can use a flash drive but you need to shut down the virtual machine and install VirtualBox Extension Pack for virtualbox version installed on your computer. And then enable usb controller in virtual machine settings.

start the virtual machine

Add the flash drive to the virtual machine to copy your files
