The OVA format is used to store data packages concerning a virtual machine. Specifically, OVE files are actually compressed OVF files, along with supporting files (.MF, .VHD, .VMDK) in form of a TAR archive.
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.
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 OVA file after converting to VMDK may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from OVA to VMDK 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 OVA to VMDK does not meet your expectations, you can simply try to find on the Internet a different version of your file in OVA format, properly converted to a VMDK file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file OVA the desired result was not achieved, you can try to change the format of OVA file to other than VMDK. 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 OVA file converted by someone else, and the attempt to convert it to VMDK 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 OVA file in its original format (without conversion to VMDK file). Such a solution will be difficult to implement, but it certainly will give the best result.
