The ITHMB ( ITHMB) file extension is a photo thumbnail database which is used by Apple iTunes, iPhoto and other Apple software. It stores thumbnails of images and videos, which represent photos and videos in the user's iPod or iPhone. ITHMB is stored on different devices and differs according to the type of device.
Compatibility and Operating Systems
ITHMB is only compatible with Apple devices running either iOS, macOS or Mac OS X, as these are the operating systems for which Apple software is available. Additionally some third-party software, such as ComSkip, is able to extract ITHMB data, however this requires more complex knowledge of ITHMB files. The format is similar to the well-known JPEG, TIFF, and BMP image formats.
Thumbnails Database File Structure
The ITHMB database consists of a set of photos and videos organized in a tree-like structure which stores thumbnails as well as other media related information. Thumbnail resolution and size vary according to the device type, which also affects the exact file structure. For example, iPhones will contain thumbnails of higher resolution than iPods as iPhones have a larger display. Additionally each thumbnail includes more information such as ISO speed, shutter speed, aperture setting, date taken among other data.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ITHMB) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ITHMB extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .ITHMB file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ITHMB extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ITHMB extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ITHMB file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .ITHMB file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .ITHMB file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ITHMB file) will be extended to the maximum.
It is also good to check
- if the .ITHMB file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
