压缩文件拷贝的问题！

[xin_zzq1]

怎么样用程序去实现某个文件夹下的一个压缩文件(.rar或者其他的压缩格式)拷贝到其他文件夹下面！

[healer_kx]

CopyFile很好说了，但是压缩要用到zlib等库，rar的算法并不公开吧？

[快乐鹦鹉]

BOOL CopyFile(LPCTSTR lpExistingFileName,LPCTSTR lpNewFileName,BOOL bFailIfExists );
　参数 类型及说明
　　lpExistingFileName String，源文件名
　　lpNewFileName String，目标文件名
　　bFailIfExists Long，如果设为TRUE（非零），那么一旦目标文件已经存在，则函数调用会失败。否则目标文件被改写

没有要求做压缩吧？

[supconsupcon]

用BOOL CopyFile(LPCTSTR lpExistingFileName,LPCTSTR lpNewFileName,BOOL bFailIfExists );

[xin_zzq1]

是的啊！我也看了Copyfile！但是我要拷贝的是一个A.CAB文件！不知道能不能拷贝

[快乐鹦鹉]

CopyFile没有说哪种文件不能拷贝啊。
偶以为因该都是可以的。

[xin_zzq1]

也就是说··从A.CAB要从个文件夹下拷贝到其他的地方··文件名还是A.CAB

[xin_zzq1]

那我去试试··谢谢啊！

CopyFile
The CopyFile function copies an existing file to a new file.

BOOL CopyFile(
LPCTSTR lpExistingFileName,
// pointer to name of an existing file
LPCTSTR lpNewFileName, // pointer to filename to copy to
BOOL bFailIfExists // flag for operation if file exists
);

Parameters
lpExistingFileName
Pointer to a null-terminated string that specifies the name of an existing file.
lpNewFileName
Pointer to a null-terminated string that specifies the name of the new file.
bFailIfExists
Specifies how this operation is to proceed if a file of the same name as that specified by lpNewFileName already exists. If this parameter is TRUE and the new file already exists, the function fails. If this parameter is FALSE and the new file already exists, the function overwrites the existing file and succeeds.
Return Values
If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks
Security attributes for the existing file are not copied to the new file.

File attributes for the existing file are copied to the new file. For example, if an existing file has the FILE_ATTRIBUTE_READONLY file attribute, a copy created through a call to CopyFile will also have the FILE_ATTRIBUTE_READONLY file attribute.

Windows CE: If the function succeeds, the return value is TRUE. If the function fails, the return value is FALSE. To get extended error information, call GetLastError.
