Decompres a zlib compressed file.

I have a file with the extension .ewb which stands for EASYWORSHIP BIBLE. I KNOW that this file contains 67 txt files in the following format,

But I have no idea how to uncompress this file to get the txt files. AND to re-compress as .ewb. I've searched alot and only found out that it contains a zlib stream and a different type of a header. But no specific information was given. Any help please... Here's an example ewb file. http://www.mediafire.com/download/2w7al3v07lespbr/niv.ewb

 

1) Why can't you use EasyWorship?
2) Why if you get these files extracted would you want to put them back in that file container?
3) If you want the files back in that format why not use EasyWorship?

 

No offence. but I dont see how ur questions are relevant to my question.

Anyway they have stopped suport for easyworship since 2009. So the bible I have contains so many errors in scripture and I want them to be fixed. there's no way to do that without decompressing the file.
