Free connection between Windows and Linux (including Linux virtual machines!

I started using virtual machines some time ago, So I installed a Linux Virtual Machine on windows. I just wanted to communicate with each other. For example, sharing a folder on windows can be accessed by linxu virtual machine, and a specified directory on Linux virtual machine can also be accessed by windows. I have discussed with some of my friends that some of the functions can be implemented. After two days of setup, I can finally implement the following functions:

1. Windows can access the directory specified by Linux (another machine on the local machine or network) or Linux Virtual Machine (another machine on the local machine or network;
2. linux (another machine on the local or network) or Linux Virtual Machine (another machine on the local or network) can access shared folders on Windows (another machine on the local or network;
3. You can use securecrt 5.0 or similar tools to access Linux on the local machine or another machine on the network );

Among them, the implementation of 1 and 2 needs to be implemented using Samba (I did this, but I don't know if there are other similar tool software ).
For specific settings, refer to the virtual machine and Samba settings. There are a wide range of online materials.

The main purpose of this article is to tell you that Windows and Linux (virtual machines) can communicate with each other!
