But "VIRTUALBOX (File Sharing)" is repeated twice which suggests to me there might be something wrong that I need to fix. And I think it works because when I launch the guest machine and open the file manager (called "Files"), it shows under "+ Other Locations" a list of several items under "Networks". I do not have Read-only checked and I do not have Auto-mount checked but I do have Make Permanent checked.

I have set a shared folder with the path and the folder name. I do not think the problem is on the host side. It is a universal way to enable a shared folder and it should work for all distributions.I have a Windows 10 Host computer and a Ubuntu guest. If you use some other distributions as a guest, look at the instructions for Debian. So, I will show you the settings for Arch Linux, Linux Mint and Debian as guest systems. In this tutorial, my host system is Arch Linux, but the host system does not matter in this case because we will do all the setting in the guest systems. Change the user permission for the shared folder.Install guest additions for your guest system.

There are several essential steps you need to follow, to enable a shared folder between the real machine (host) and the virtual machine (guest): I will also show a universal way that should work for any Linux guest distribution. So, I will show you how to enable a shared folder in Virtualbox for Debian, Linux Mint/Ubuntu, and Arch Linux as guest systems.

However, configuring the Virtualbox to share files between your main system and the system you installed in a VirtualBox is not trivial. VirtualBox is a very useful tool to install operating systems inside the main system.
