I want to delete everything custom.

[br3akth3w1nd]

I got hundreds of custom units, items and everything. I want to get rid of them but if I start deleting them one by one it will take so much time.. Is there a way to delete them faster? I dont want anything custom in my map. Maybe somehow with jass craft?

1. Make a blank map in World Editor, save it.
2. Open that blank map in MPQMaster.
3. Extract files with the following extensions;
.w3a, .w3t, .w3h, .w3q, .w3u, .w3b, .w3d, and .wts.
4. Open your custom map and replace all those files.
5. You're done!

That should all of the following:
Units, items, destructibles, doodads, buffs, effects, abilities, and strings (where a lot of text is kept, mainly item/ability names/descriptions).

I did it without MPQ editor..
