4.1 viminfoIn Vim, Vim is automatically recorded and saved in the ~/.viminfo file. This is to facilitate the next processing, such as: Vim when you open the file, the cursor will automatically appear in the last location. The original searched string, the newly opened file is automatically highlighted.
The ~/.viminfo file is automatically generated by the system.


4.2 VIMRC (Global:/ETC/VIMRC, User: ~/.VIMRC)The VIMRC file is a VIM environment settings file. The overall vim setting is in the/ETC/VIMRC file. Modifying the/ETC/VIMRC file is not recommended, and each user can set up vim in the user's root directory and create a new ~/.VIMRC. Vim has more configuration options.
