Lazarus doesn't include support for ZIP files, AFAIK. A ZIP file is a 
container of compressed streams. So you have to parse the ZIP file 
structure and then use TDecompressionStream on the stream you want to 

I wrote a decent ZIP wrapper unit for FPC and Delphi. In FPC it uses 
"paszlib", in Delphi it uses "System.ZLib".
But it depends on some of my internal classes. Maybe I will rewrite it 
so that it could be included into FCL. But I really have a lot of work 
now :(
