It doesn't seem to be possible to convert Nokia messages (.vmg) to ARC backup file. You might have been looking for the opposite arc to vmg conversion however, which is probably possible, but vmg to arc conversion seems very unlikely.
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.
