paszlib is a Pascal conversion of the standard zlib library: you don't need any external dependencies. It was implemented by Jacques Nomssi Nzali (his old homepage is dead, see a continuation of the project here). It is used in the FCL to implement the TCompressionStream class.
This class lets you compress and decompress .zip files.
The main unit of this package is paszlib. There are other, auxiliary units, but the only unit that needs to be included in a typical program is this one.
TZipper
TZipper implements support for compressing and decompressing .zip files, but does not support all zip compression methods.

예제
Zip files
첫번째 인수에 파일이름을 입력하여 zip 파일을 생성할 수 있습니다. 이후 인자 파일이름을 추가하여 zip파일에 포함합니다.
다음은 생성하는 예입니다.
zipper newzip.zip autoexec.bat config.sys
uses
Zipper;
var
OurZipper: TZipper;
I: Integer;
begin
OurZipper := TZipper.Create;
try
OurZipper.FileName := ParamStr(1);
for I := 2 to ParamCount do
OurZipper.Entries.AddFileEntry(ParamStr(I), ParamStr(I));
OurZipper.ZipAllFiles;
finally
OurZipper.Free;
end;
end.
압축 풀기
c:\test.zip 압축파일의 모든 파일을 c:\windows\temp\ 디렉토리에 풀기
uses
Zipper;
var
UnZipper: TUnZipper;
begin
UnZipper := TUnZipper.Create;
try
UnZipper.FileName := 'c:\test.zip';
UnZipper.OutputPath := 'c:\windows\temp';
UnZipper.Examine;
UnZipper.UnZipAllFiles;
finally
UnZipper.Free;
end;
end.

In Lazarus, drop a TMemo, TButton, TEdit and TFileNameEdit on a form. Clicking the button will read the zip file in FileNameEdit, extract the file specified in the Edit box, and display the content in Memo.
uses
Zipper;
...
procedure TForm1.Button1Click(Sender: TObject);
begin
ExtractFileFromZip(FileNameEdit1.FileName,Edit1.Text);
end;
procedure TForm1.DoCreateOutZipStream(Sender: TObject; var AStream: TStream;
AItem: TFullZipFileEntry);
begin
AStream:=TMemorystream.Create;
end;
procedure TForm1.DoDoneOutZipStream(Sender: TObject; var AStream: TStream;
AItem: TFullZipFileEntry);
begin
AStream.Position:=0;
Memo1.lines.LoadFromStream(Astream);
Astream.Free;
end;
procedure TForm1.ExtractFileFromZip(ZipName, FileName: string);
var
ZipFile: TUnZipper;
sl:TStringList;
begin
sl:=TStringList.Create;
sl.Add(FileName);
ZipFile := TUnZipper.Create;
try
ZipFile.FileName := ZipName;
ZipFile.OnCreateStream := @DoCreateOutZipStream;
ZipFile.OnDoneStream:=@DoDoneOutZipStream;
ZipFile.UnZipFiles(sl);
finally
ZipFile.Free;
sl.Free;
end;
end;
