　　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;

};
