Figure 5-3: The structure of thumbnail caches in Ubuntu and Kubuntu
The hexadecimal below was extracted from an Ubuntu operating system and
shows the directory information for .thumbnails. In this example, the directory
contains a single sub-directory named normal. The normal directory holds
subrecords with visual thumbnails up to 128x128 pixels in size. Up to two
further directories may be found in’ .thumbnails’: large and fail. The two further
directories do not exist because they are only created when they are required
by the system.
