File extension: iTHMB
Stands for: iThumbnail
Type: Image media file
Company/creator: Proprietary file of Apple Computer Inc.
iTHMB files are specifically for iOS devices (iPod and iPhones in this case). Opening these on other operating systems, such as on your PC, can be challenging. These files can be transferred easily, like any other file, but your PC does not have a default program that can open these thumbnail images for viewing unless you use an iTHMB converter to change these images into another format (for example, a TIFF image). Correct iTHMB viewer software is required to view and to convert the iTHMB file.
