Clear thumbnail cache - Whenever you view a document or media files like photos and videos, Windows shows a preview of that file instead of the generic thumbnail icons. These previews are pretty helpful as they let you quickly recognize the file you are looking for. Generally, these preview thumbnails are cached so that Windows can show the previews quickly when you re-open the File Explorer or the target folder. However, from time to time, the thumbnail cache gets corrupted and you don't see proper thumbnail previews.
This happens due to any number of reasons like sudden power loss, accidental deletions, etc. In those situations, all you have to do to fix thumbnail cache is to clear thumbnail cache. Here's how to clear thumbnail cache in Windows 10, 8, and 7.
Windows has two different methods to clean thumbnail cache. The first one is to use the built-in Disk Cleanup tool and the second one is to use the Command Prompt. I will show both the methods, follow the one that is easy for you.
Note: though I'm using Windows 10, the procedure to delete thumbnail cache is same for Windows 7 and Windows 8.
