why i cannt use winmpq open w3m file?

i just can use it open mpq file ,but when i open w3m file, the winmpq say the w3m is not mpq .

I already put the storm.dll in the same dir

winmpq doesn't work on w3m files unfortunatly, you have to use mpqview.

works for me, try replacing the storm.dll that in your /windows/system map.. I did that

OK lemme clarify it:
WinMPQ works with retail W3M files!
You just need to get the right "patched" one.

Make sure you read the readme.txt and followed the steps.
