I cannot find the libraries and its settings

Good day experts,
I want to backup my Libraries and all its contents and settings and make it a single file. For example:
Doc.lib: This file composed of links with all its folders and the information on the icons that are used for the library and its view type such as thumbnails and etc… This is just an example. I am not sure if there is such a file with this kind of settings that exists and I'm not sure on how to make a backup for this. So I am asking everyone if I can make a backup of all the libraries on my computer. If so, please send me some suggestions.
