Help with out of memory when using zip

[jicman]

Greetings!

I have this program that zips a file and everything works 
perfectly, if the
files are small enough.  But, I am having to zip files that are 
getting more
and more extreme in size and I am running out of memory.  Here is 
the output
when executing a small program to zip a folder:

  0:36:59.76>zipafile
Zipping file no 0 huge\0.pdf
  ** PLEASE WAIT FOR FILE #0 TO BE ZIPPED **
Zipping file no 1 huge\1.exe
  ** PLEASE WAIT FOR FILE #1 TO BE ZIPPED **
Zipping file no 2 huge\2.exe
  ** PLEASE WAIT FOR FILE #2 TO BE ZIPPED **
Zipping file no 3 huge\updates\p.zip
  ** PLEASE WAIT FOR FILE #3 TO BE ZIPPED **
Zipping file no 4 huge\updates\q.html
  ** PLEASE WAIT FOR FILE #4 TO BE ZIPPED **
Zipping file no 5 huge\updates\z.exe
  ** PLEASE WAIT FOR FILE #5 TO BE ZIPPED **
finished all files...
  ** PLEASE WAIT FOR ZIP FILE TO BE CREATED **
Error: Out of memory

This is the program in question...

import std.stdio;
import std.file;
import std.date;
import std.zip;
import std.zlib;
import jic.libs.MyFile;

int main(char[][] args)
{

   char[] folder = r"c:\tmp\huge";
   ZipAFolder(folder);
   return 0;
}

void ZipAFolder(char[] zipFolder)
{
   char[] fdname = std.path.getDirName(zipFolder);
   char[][] allfiles = std.file.listdir(zipFolder,"*");
   char[] zipFile = zipFolder ~ ".zip";
   int FilesCnt = 0;

   std.zip.ZipArchive zr;
   zr = new std.zip.ZipArchive();
   int one = 0;
   foreach(char[] f; allfiles)
   {
     char[] f0 = std.string.replace(f,fdname ~ "\\","");  // 
Filename
     writefln("Zipping file no " ~ std.string.toString(one) ~ " " 
~ f0);

     ArchiveMember am = new ArchiveMember();
     am.compressionMethod = 8;
     am.name = f0;
     //am.expandedData = cast(ubyte[]) f.read();
     am.expandedData = cast(ubyte[]) f.read();
     am.expandedSize = am.expandedData.length;
     FileData fd0 = GetFileInfo(f);
     long usedT0;
     if (fd0.creationTime > fd0.modifiedTime)
     {
       usedT0 = fd0.creationTime;
     }
     else
     {
       usedT0 = fd0.modifiedTime;
     }
     am.time = std.date.toDosFileTime(usedT0);
     zr.addMember(am);
     writefln(" ** PLEASE WAIT FOR FILE #" ~ 
std.string.toString(one) ~ " TO
BE ZIPPED ** ");

     one++;
   }
   writefln("finished all files...");
   writefln(" ** PLEASE WAIT FOR ZIP FILE TO BE CREATED ** ");
   std.file.write(zipFile, cast(byte[])zr.build());
   writefln(" ** " ~ std.string.toString(one) ~ " FILES ZIPPED ** 
");
   writefln(zipFile ~ " created.");
   //return 1;
}

As you can see, the last two writelns do not get printed because 
of the Out
Of Memory.  Any help would be greatly appreciated.  Thanks.
