Current questions and answers regarding the map editor.

Well, I think this isn't a new question, but please tell me step by step what to do. I want to edit an existing map that comes with the game. I found on the forum that I need to extract the "maps" folder from the data file. I extracted it, but there appeared files with names like "ground terrain.bin," "mM2_2_pic.dds," "map-tag.xdb," and in each map (M2), there are a bunch of such files. But the editor only understands files with the ".h5m" extension, and these seem to be for some design programs, etc. Tell me what to do so that I can edit them.
