You cannot convert .pvs configuration files from Parallels Desktop virtualization software to another of its file types - hdd (virtual hard disk), which means pvs to hdd conversion is unlikely. These files are both needed in order for the virtual machine to work and contain different kind of data.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
