It seems both ..dmse and .dmss files are from Roxio software and both used for projects. However it does not seem possible to convert one to another or somehow transfer the data. We haven't found any related information on internet that could help us with this topic, so if you know anything relevant, please let us know.
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.
