As a result, the iTunes synchronization is faster and smoother.
This is because the iTHMB file contains uncompressed graphic data. ITHMB files can be significantly larger in size than the original files. A new file is created and incremented when the file has reached its maximum size. Previous versions use the following: F#_#.ithmb (for example: “F3039_1.ithmb”). Each iTHMB file can store numerous thumbnails but each image is of the same size as is reflected in the name. For more recent versions the file is named using the following naming convention: AxB.ithmb (for example: “hmb”). Naming of the iTHMB files is also dependent on the iOS version. The iTHMB files were located in the “Thumbs” subfolder. Earlier iOS versions store the index files in the mobile/Media/Photos/ directory with the name “PhotoDatabase”. More recent iOS versions automatically store the index file as “Photos.sqlite” in the mobile/Media/PhotoData/ directory and iTHMB files are stored in the “Thumbnails” subfolder. There are several factors that determine the name and the location of the iTHMB and index files including: the iOS device type (iPod, iPhone, iPad), the iOS version of the device, and whether the iTHMB file has reached its maximum size. Storage of thumbnail images specific to the iOS device display mode and screen size. Stores metadata and subfolders to contain iTHMB files. The photo cache is created to store the following: Item: ITunes creates a cache folder on the hard drive when you sync an iOS device (such as an iPod, iPhone, or iPad), to a computer (Mac or PC). The file is saved to the original device and to your PC. On a PC, an iTHMB file is created when syncing an iOS device with iTunes. The Ithmb(.ithmb) is a collection of small thumbnail images stored together in one file for convenient viewing (for an iTHMB view you generally need a special device). We'd like to take a closer look at this process.
