ERPNext folders via VirtualBox

Hello there.

I am kinda new to ERPNext and to be honest to coding too. I am trying to create a website within ERP and i would like to use an external template to do this, but I don’t know how to access the files via VirtualBox.
Can someone help me out with this.

PS: sorry if this this isn’t the right place to post this issue.

Any help, suggestion will be appreciated.
You all have a good day!

Maybe by configuring FTP you can access the files.
