Blend-Files Previews#
A blend-file can store previews, both for itself, and for some of its data-blocks. You can disable writing any previews when saving a blend-file using the Save Preview Images setting from the Сохранение и Загрузка section of the Preferences.
Blend-File Preview#
Blender saves by default a small preview of current scene in the blend-file. This will show in the Thumbnail view of the File Browser.
During its installation, Blender also adds a small tool to your OS, that will allow your system file browser to show those previews as file thumbnails as well.
Data-Blocks Previews#
Blender will automatically generate previews for some type of data, mainly the ones related to shading (like images, textures, materials, lights and world shaders).
It can also store previews for scenes, collections and objects, but those need to be generated manually.
These previews can then be used by the Thumbnail view of the File Browser, when linking or appending data-blocks.
Refresh Data-Block Previews#

Refresh all data-block previews that can be automatically generated by Blender (shading-related ones), in the current blend-file. You still need to save the file if you want to write them to the drive.
Batch Generate Previews#

This is currently the only way to generate and store in blend-files previews for scenes, collections and objects. Note that since this involves a lot of rendering, even of small sizes, the process may take some time to complete.
