KMA (kmg?) files are a self contained format.
KMH files, as Dale has pointed out, are "indexing" files that reference your MP3G, ZIP, etc. files that remain unmodified by the separate KMH files.
If you want to convert the MP3G, ZIP, etc. files called by KMH files, then
don't delete the originals so the KMH's still work. Then, your converted copies have nothing to do with your KMH files.
As Dale wrote, why would you want to do anything with KMH files?
