What does w3x stand for?

[Cheezeman]

Does anyone know what the X in the W3X file format name stands for?

 

[Rahko]

It means it's a Frozen Throne map and requires the Expansion Pack to be played.

 

[Cheezeman]

I guess the X might stand for Expansion. Got any source?

 

[SharSash]

I think it follows the same logic as MS office's doc and docx, xls and xlsx, just a newer format, in this case an expansion

 

[Rahko]

Yes, I always thought it stood for "eXpansion", but in theory it could mean anything. Like SharSash above said, they could have used any other letter just as well, it's just something they decided that stands for a newer version of the file type.

Why in the world would anyone care about what that stands for...
What does the M in w3m stand for too?

 

[IcemanBo]

As a guess I would say "w3m" stands for "warcraft 3 map", as it was the first map format.
