Again for the sake of simplicity, having a single file type manager in my opinion is less functional, if this application fails for some reason, no file type will be recognized, and it will also be difficult to identify who caused the problem.
With descriptors this cannot happen, when a file is not recognized, it will only be a descriptor or datatype that will be the culprit and then based on the extension you will understand where to intervene.
The conversion of music files, archives, images, I did it on Dopus4, but the same procedure can be done on Wanderer, just use a menu manager like "UserMenus"
