Hello,

I've tried to generate .gz files with the Zlib library given in BDS 2006 and with the Zlib Library 1.2.3 found online, and they don't generate valid .gz files (WinRAR or readgzopen() in PHP, don't want to open generated files).

Someone can help me?

FileTools v.2.3  
By J. Rathlev, IEAP. FileTools is a collection of several objects to copy, pack files (gz, Zip and Zip64 format are supported) and unpack files (only gz format) using a separate thread. For packing and unpacking the zlib-routines from Jean-Loup Gailly and Mark Adler are used.

I have found the answer alone ^^

I have used the Abrrevia Library!

program Test;

{$APPTYPE CONSOLE}

uses
  SysUtils, Classes, AbGZTyp;

var
  gzFile: TAbGzipArchive;
begin
  //Pack
  gzFile := TAbGzipArchive.Create('test.txt.gz', fmCreate);
  gzFile.load();
  gzFile.AddFiles('test.txt',0);
  gzFile.Save;
  gzFile.Destroy;

  //Unpack
  gzFile := TAbGzipArchive.Create('test.txt.gz', fmOpenRead);
  gzFile.Load();
  gzFile.ExtractAt(0, 'test.unpack.txt'));
  gzFile.Destroy;
  Readln;
end.
