Notes about the MDBACKUP 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 MDBACKUP file type is primarily associated with 'IPhone' by Apple Inc.. An iTunes backup of the iPhone is stored in a backup folder in ~/Library/Application Support/MobileSync/Backup. Each subdirectory contains the backup from a different device. MDBACKUP files, found in the device directories, are property lists and are created in a compressed binary format.
