Files with .VDI extension contain virtual disk images along with associated metadata. VDI is the native image format for VirtualBOX, a system virtualization software. VDI is a disk image file-container loaded as guests by VirtualBox hypervisor on given machine (referred to as host).
VHD is a file which contains a virtual image of a hard drive , used by Microsoft Windows Virtual PC. Single VHD file may contain all data stored on a physical hard drive, saved exactly in the same structure – partitions, system files, regular files and folders.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the VDI file after converting to VHD may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from VDI to VHD to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting VDI to VHD does not meet your expectations, you can simply try to find on the Internet a different version of your file in VDI format, properly converted to a VHD file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file VDI the desired result was not achieved, you can try to change the format of VDI file to other than VHD. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your VDI file converted by someone else, and the attempt to convert it to VHD on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the VDI file in its original format (without conversion to VHD file). Such a solution will be difficult to implement, but it certainly will give the best result.
