What is a thumbnail cache?
A Thumbnail cache is a copy of all of your documents, pictures, and video thumbnails stored in a file. Windows 10 generates and stores a copy of thumbnails for all documents, videos, and images for faster access so they can be displayed without any delay when you open a folder with one of the thumbnails supported view. This means, whenever you open a folder containing videos, documents, or pictures in thumbnail supported view, Windows uses thumbnails saved in the thumbnail cache instead of every time generating new for them. These thumbnail caches enable Windows 10 to show thumbnails display quickly.
On Windows 10, all the thumbnail cache files are stored under profile. You can access the same by navigating to C:\Users\UserName\AppData\Local\Microsoft\Windows\Explorer (assuming “C” is your Windows installation directory, if you have installed Windows on other than C:\ drive, then the path will change accordingly). By default, these items remain hidden, and one needs to unhide to see them.
