　　本程序示例如何将多个文件合并成一个文件，并能够自分解。此技术在制作安装程序时非常有用。我在本网站学到了此技术，并将他整理扩展，能够合并文件和目录，个数不限。
　　核心程序包括一个合并文件类 CCombineFiles，一个分解文件的类 CExtractFiles 和一个表示文件或目录信息的数据类 FileInfo 文件和目录的信息都由FileInfo类表示。此类定义如下：

class FileInfo  
{
public:
	const FileInfo &operator = (const FileInfo &fi);
	FileInfo(CString szFileName, UINT nFileSize, UINT nPos, char type = 0);
	FileInfo();
	virtual ~FileInfo();

public:
	CString szFileName;
	UINT nSize;
	UINT nPos;

	char type; // d --- directory , f --- file , other --- no define 
}; 

class CCombineFiles  
{
public:
	bool Combine(CStringArray &fileList, CString szToFileName);
	CCombineFiles(CString szExeFileName);
	virtual ~CCombineFiles();

public:
	bool WriteFileInfo(FileInfo fi, FILE *fp);
	bool WriteString(CString szStr, FILE *fp);
	bool WriteListInfo(CArray
  
  
   
    &fiList, FILE *fp, UINT nStartOffset);
	bool CombineFile(CString szFileName, FILE *fp);
	bool CombineDirectory(CString szDir, FILE *fp);
	CString m_szExeFileName;

}; 
  
  

class CExtractFiles  
{
public:
	bool ExtractFiles(CArray
  
  
   
    &fiList, CString szPath);
	bool ReadFileList(CArray
   
   
    
     &fileList);
	CExtractFiles(CString filename);
	virtual ~CExtractFiles();

public:
	bool ExtractDirectory(FileInfo fi, CString szPath, FILE *fp);
	bool ExtractFile(FileInfo fi, CString szPath, FILE *fp);
	bool ReadString(CString &szStr, FILE *fp);
	bool ReadFileInfo(FileInfo &fi, FILE *fp);
	bool ReadListInfo(CArray
    
    
     
      &fiList, FILE *fp, UINT &nStartOffset);
	bool ReadFileList(CArray
     
     
      
       &fiList, FileInfo dir);
	CArray
      
      
        m_fileList; CString m_filename; }; 
      
     
     
    
    
   
   
  
  

	szExeName = "G://COM//TestEvent//TestBp//bp.exe";
