What is an .DTHUMB file?

.DTHUMB is Android Data Thumbnail

A DTHUMB file is a thumbnail that contains metadata for a specific media file, such as an image or video. It is a descriptor file automatically generated on Android devices that provides small thumbnail images and basic information about media files.

DTHUMB files are saved in a proprietary format that begins with a header, followed by binary thumbnail data. The end of the file contains technical information about the referenced media file. DTHUMB files are generated by the Android OS and are typically hidden (invisible) since they are not meant to be opened manually.
