c++builder ZIP文件解压与压缩（ZLIB DLL调用），目录复制与删除整合的自用类，可自行扩张！

头文件：ZipAndFile.h

//---------------------------------------------------------------------------#ifndef ZipAndFileH#define ZipAndFileH#include <Classes.hpp>//---------------------------------------------------------------------------class ZipAndFile{private:public:ZipAndFile();~ZipAndFile();//ZIP操作bool DoZipfile(String DoZip,String ZipFilename,String SourceFile,bool Check);//复制目录bool MyCopyFiles(AnsiString FromFile,AnsiString ToFile);//删除目录bool deldir(char* dir_fullpath);};#endif

使用方法：包了头文件后：

ZipAndFile *TZipAndFile=new ZipAndFile();//新建对像//删除temp文件夹dir_fullpath=(ExePath+"web_back").c_str();//删除web原文件if(TZipAndFile->deldir(dir_fullpath)) ｛｝delete TZipAndFile;// 删除对像

DLL两个接口：

//压缩，bUtf8为false将支持路径与文件内包含中文

BOOL ZWZipCompress(LPCTSTR lpszSourceFiles, LPCTSTR lpszDestFile, bool bUtf8 = false);

//解压
BOOL ZWZipExtract(LPCTSTR lpszSourceFile, LPCTSTR lpszDestFolder);
