You must have seen small previews for files and folders in Windows 10. These thumbnails make it convenient to browse files and folders in file explorer. Sometimes these thumbnails are not displayed correctly for some files and folder. This happens when thumbnail cache on Windows 10 gets corrupted.
All the thumbnails displayed in Windows OS are stored in a database called thumbnail cache database. As amount of files and folders grew, the size of cache database also increases.
