File with VMDK extension is a VMware virtual machine disk file. Such file contains files and folder that comprise a virtual disk created using Vmware software. Single VMDK file can contain information about one or more virtual disks.
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).
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 VMDK file after converting to VDI may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from VMDK to VDI 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 VMDK to VDI does not meet your expectations, you can simply try to find on the Internet a different version of your file in VMDK format, properly converted to a VDI file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file VMDK the desired result was not achieved, you can try to change the format of VMDK file to other than VDI. 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 VMDK file converted by someone else, and the attempt to convert it to VDI 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 VMDK file in its original format (without conversion to VDI file). Such a solution will be difficult to implement, but it certainly will give the best result.
