What is HDD file?
The HDD (.hdd) file extension is associated with the Parallels Desktop application developed by Parallels, Inc. It is a type of disk image used to create and manage virtual machines, allowing users to run multiple operating systems on the same computer. HDD files contain the entire content of a virtual hard disk, including the guest operating system, its settings, any installed applications, and the data saved on the virtual drive.

Software, that you can use to convert
How to convert the file from HDD to VHD?
To successfully convert the HDD file to VHD, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.HDD). The next step is to select the target format from the list, in this case VHD (usually converters allow you to convert to several different formats, so check out their features - maybe one of the available formats will suit you more than VHD).
What is a file conversion?
A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. HDD to VHD. To obtain a matched structure of the data, it is necessary to use an appropriate converter.
Program for converting HDD files to VHD files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension VHD, while before this step we had the HDD file). For the programs, the difference is on a much higher level – either the application will be able to open a new VHD file, or not.
