Thumbnail cache
Definition
A store of small preview images generated by the OS or applications when media is first viewed. On Android the primary cache is stored in a .thumbnails directory or a MediaStore database; on iOS thumbnails are managed by the Photos framework in DCIM and PhotoData directories. Caches are evicted on their own schedule, independent of source file deletion.
