What is a .hdd file?

A .hdd file is a hard disk image file, essentially a complete sector-by-sector copy of a physical hard drive or a partition. It contains all the data, file systems, and boot sectors present on the original drive. This makes it useful for backups, system recovery, and virtual machine environments. Hard disk images allow users to create exact replicas of their systems, enabling them to restore their data and operating system to a previous state in case of hardware failure, data corruption, or system crashes. They are also commonly used in virtualization to create virtual hard drives for virtual machines, allowing them to run different operating systems and applications in isolated environments. The .hdd format is often associated with specific virtualization software or disk imaging tools, and the exact structure and format of the image file can vary depending on the software used to create it. These files can be quite large, often mirroring the size of the original hard drive or partition.
