How to Enable or Disable Thumbnail Previews in Windows 10 File Explorer The Thumbnails do not appear in the following Three View types – Small icons, List and the Details. Out of the Eight View types in the Windows File Explorer, the thumbnails are visible in the following five – Extra Large Icons, Large Icons, Medium Icons, Tiles, and Content. This loads the Windows File Explorer a lot quicker, and the computer feels faster. When Icons are used instead of Thumbnails, Windows only needs to load one icon for all of the images stored in that folder.
You can disable the Thumbnails by using the Icons instead.
The user has to wait for the thumbnails to load, which makes the computer feel slower. When you have the thumbnails previews enabled, opening a folder that has many images takes a lot of time, as Windows has to load the thumbnail preview of each image file from the Thumbnail Cache. All those files that have some sort of visual content related to them can have thumbnails such as an image file, a video file, or a song with album art. Thumbnails are the small sized version of each image that previews the contents of that image.
