You can see in the left folder sf_Compiler and in the top right how I configured in VirtualBox settings and bottom right the folders that I should be seeing in my VM which are present in the host.
Instructions are from here: https://courses.edx.org/courses/course-v1:StanfordOnline+SOE.YCSCS1+3T2020/7b74698308574f3c89d2ed498f26a019/
VM for the Stanford compiler course on Edx.
What else do I need to do to see all my host folders in the VM?
I tried clicking Insert Guest Additions CD from Device menu but it doesn't do anything.
I'm also unable to cd into that directory from terminal in the VM
compilers@compilers-vm:/media$ cd sf_Compiler
bash: cd: sf_Compiler: Permission denied
compilers@compilers-vm:/media$
I tried sudo cd as well.
