Maybe it is possible to convert between various Nick-O-Matic Design Factor projects (.npf and .ncb) directly in the program. However, we could not verify if the latest version of the program can work with the older projects and if such npf to ncb conversion is actually feasible.
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.
