Notes about the ITHMB file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The ITHMB file type is primarily associated with 'iPod photo' by Apple Inc.. iPod photo displays 25 full-color thumbnails at a time. Images are displayed when a thumbnail is clicked on. Thumbnails are kept in a single file with this extension.
