Benefits of shared folders

Virtual Box has a function to share the expanded directory with the host OS
What are the benefits of this?

If i think about it simply, it seems that the capacity is likely to double. If there is a merit

  • Since the host OS also has files, it can be changed by operations from the host OS
I only think about

, but is this merit so great?

I ’d love to hear from you, thank you

  • Answer # 1

    I already have an answer.


    If you think simply, the capacity seems to be doubled and I think the disadvantages are great

    In the context of demerits, "capacity" means disk usage. That won't double. You share a folder (directory) on the host machine. The image looks like sharing a folder on the file server. In fact, you can do the same thing with a file server, but it's a shared folder that is easier and faster to use.

  • Answer # 2

    Files can be shared between guests and hosts.
    If you feel merit, you can use it. If you don't feel it, you don't have to use it.
