How to access hassio file system on VDI?

How does one access the file system on a hassio VDI?

I would like to install a custom addon, though it requires me to physically copy a directory into the custom_components directory of my Home Assistant installation. I would know how to do this if HA was installed in Windows or Linux, but the hassio file system is not readily available to me.

You should be able to use one of the SSH, VSCode, or Samba addons to access that path.

I can access the path with vscode. I can edit/create codeā€¦is there a command to copy physical files?

Edit: Looks like I can simply copy & paste into the directories.

Yes. VSCode has an option to upload any file. Right click on a folder on left view.
