Shared Folders: Basic (short) Question

[Virtual Adam]

Hi, I'm new to virtualbox, and I think this is a fairly basic (and I'm guessing obvious) question, but the official documentation doesn't give a straight answer, and I haven't found a clear explanation online:

What exactly to auto-mount and make permanent do (checkboxes when adding shared folders)? What is the difference between them?

Thanks,
Adam

Make permanent retains the link to the host share but does not mount it.
Auto-mount will do just what it says and mount the share at boot without user intervention of setup properly.
