As it says in the description of custom MIME types, you can change the MIME type only for DSF and DFF files. This capability is needed for these specific types because there has been significant divergence between audio products over what MIME types should be used for these files. Fortunately, this divergence is now being resolved to an accepted industry standard (the default MinimServer values).

For other MIME types where established industry standards exist, MinimServer does not allow the MIME type to be changed. This is consistent with MinimServer's strict conformance to industry standards and specifications.
