it works well for normal archives.
but how to process zip archive ~1GB ?
it takes a long of RAM.

Hmm... it's unfortunate that ZipArchive doesn't take a file 
descriptor. As a workaround, you can use memory mapping:

import std.stdio, std.zip, std.file, std.mmfile;

int main()
{
   auto mmfile = new MmFile(File("c:/test.zip", "rb"));
   auto zip = new ZipArchive(mmfile[]);
   foreach (item; zip.directory) {
     writeln("processing ", item.name, " ...");
     // processing item...
   }
   return 0;
}

This could be added to the ZipArchive online docs.
